Quiet, Swept, and Five-Blade Swept Turbofan Propellers

30-61-00-00 Description and Operation
The Propeller De-ice System includes: an electrically heated boot for each propeller blade, slip rings,
brush assemblies, timer, control switch, and an ammeter. When the control switch is activated, the
ammeter registers the amount of current (18 to 24 amperes) passing through the system. The
current flows from the timer through the brush assemblies to the slip rings, where it is distributed to
the individual propeller de-ice boots. If the current draw should exceed design limitations, a circuit
breaker integrated into the control switch will cut power to the timer. Heat, produced by the heating
elements in the prop boots, reduces the adhesion of ice on the propeller. Adhesion thus reduced, the
ice is removed by the centrifugal effect of the propeller and the blast of the airstream. The propeller
blades are equipped with single-heating-element de-ice boots. Power to these boots is cycled in 90-
second phases. The first 90-second phase heats all the prop boots on the RH propeller. The second
phase heats all the de-ice boots on the LH propeller. The de-ice timer completes on a full cycle every
three minutes. As the timer moves from one phase to the other, a momentary deflection of the
propeller ammeter needle may be noted.

NOTE: The heating sequences for the De-ice Boots noted in the preceding section
are the sequences which are in evidence during normal operation. However,
due to the fact that the timer does not return to a given point when the control
switch is shutoff, sequential operation may start at any point in the cycle.
Power to the heating elements in the propeller boots is cycled in a
continuous programed sequence.

30-72-00-10 Troubleshooting
Perform a functional test of the Bypass Door and Particle Separators in accordance with the
Beechcraft Super King Air 200 Series Maintenance Manual, Chapter 30.

NOTE: The curved turning vane tends to try to deploy the Particle Separator due to
aerodynamic forces. Account for this when adjusting the microswitches for
the annunciator light.

When the Inertial Particle Separators are deployed at high indicated airspeeds, binding in the
Beechcraft actuation mechanism can cause the separator doors to remain deployed as long as the
airspeed is high. This can be caused by parts of the Beechcraft mechanism that are worn, broken, or
binding. Examine components every time the lower cowling is removed or at 200 hour intervals,
whichever occurs first.
There are no approved repairs on any Raisbeck Ram Air Recovery System component. Replace any
damaged or worn components.
1. Disconnect the Particle Separator Actuator Rod and inspect the piano hinge for condition,
security, and freedom of movement.
2. Inspect rod ends for condition, security, and freedom of movement.
3. Adjust the linkage in accordance with Chapter 30-72-00-20 of this manual.

King Air 200 Series Maintenance Manual, Chapter 30.
Bypass Door Adjustment
Make the adjustment of the Bypass Door as given in the Beechcraft Super King Air 200 Series
Maintenance Manual, Chapter 30. The Bypass Door must have a tight fit in the nacelle opening when
the door is closed to ensure the effectiveness of the Ram Air Recovery System.
Particle Separator Adjustment
1. Adjust the length of the linkage as necessary so that the Particle Separator assembly touches the
entire width of the fixed turning vane.
2. Preload the Particle Separator assembly by turning the linkage adjustment a maximum of one-
quarter (¼) turn.

CAUTION: EXCESSIVE PRELOAD CAN RESULT IN DAMAGE.

3. Secure jam nuts with .032 inch stainless steel lockwire.

4. Cycle the Particle Separator and verify smooth operation and annunciation.
5. Adjust the microswitches as needed for annunciation.

NOTE: The curved turning vane tends to try to deploy the Particle Separator due to
aerodynamic forces. Account for this when adjusting the microswitches for
the annunciator light.

This section reserved.
Rigging Adjustment 100, A100, B100, F90, 200 Series, B300/B300C
Make the adjustments given below in the sequence given. Each time the door linkage is adjusted,
the over-center dimension, the tire clearance, and the fit of the closed gear doors must be tested.
1. Jack the aircraft per the applicable Beechcraft King Air Maintenance Manual.
2. Adjust the landing gear as given in the applicable Beechcraft King Air Maintenance Manual
Chapter 32.
3. Remove the bolt, washer, nut, and other cotter pin from the clevis, and disconnect the lower
clevis from the plate attached to the clevis. Examine the cam, link, and both clevises for correct
and smooth operation throughout normal travel. Make an adjustment to the clamp-up (torque) of
the pivot bolts.
4. With the gear fully extended and the cam against the door hinge extrusion:
a. Put the upper edge of a straightedge at the centerline of the link mounting bolt and the lower
edge at the centerline of the bolt that attaches the lower clevis to the plate on the door as
shown in FIGURE 1.
b. When each door locks in the open position make sure that the center line of the upper clevis
bolt is not over-center by more than .06 in as measured from the attachment point of the
bottom clevis to the linkage.
5. With the landing gear retracted, adjust the clevis that connects the upper link to the cam until the
door closes for a tight fit.
6. Ensure the actuator roller aligns with the center of the cam slot and does not bottom out when the
doors are closed. Examine for a clearance of .04 to .08 inch between the actuator roller and the
adjusting block of the cam. If necessary, change the position of the adjusting block to get the
correct clearance.
7. Retract the gear as necessary to examine for a minimum clearance of 1.0 inch between the tire
and the door. If the door clearance is satisfactory, retract the gear and make sure that the doors
are correctly closed. If the doors do not close flush or are too tight, adjust the door linkage again
to achieve correct fit. Adjust the upper and lower pivots, or change the location of the slotted
attachment plate on the door.
8. Apply 25 pounds towards the gear at the lower center edge of the door to make sure that the door
linkage is correctly over-centered when open. This ensures that each door is locked open to
withstand the air loads during takeoff and landing. Adjust the door as necessary if the door
closes under the 25 pound load.
9. Operate the landing gear several times to make sure that the doors close correctly when the gear
is retracted, and that they stay open when the gear is extended.

51 Standard Practices and Structures

51-00-00-00 Description
This section provides information for acceptable repairs and repair limits for selected Raisbeck
Systems components. In general, the repair methods used on all Raisbeck Systems may be in
accordance with AC43.13-1A Aircraft Inspection and Repair Manual and AC43.13-2 Aircraft
Alterations Manual. The repair information below is recommended in addition to the information given
in AC43.13-1A and AC43.13-2.
It is the responsibility of the owner or facility performing the work to obtain approval of their particular
repair.

51-00-11-00 Composite Description

This section gives instructions for the repair of fiberglass components made from epoxy resin that is
reinforced with several layers of glass fabric. Some components use a sandwich construction with a
non-metallic core. This section describes two methods of repair – Wet Layup and Prepreg Layup.
The wet layup repair method is acceptable on all components (except on the leading edge for
damage greater than 2 inches in diameter). The wet layup method uses fabric impregnated with
epoxy resin during repair work. This method will cure at room temperature.
The prepreg layup uses the preimpregnated fabric with epoxy resin and requires a control
temperature (250 F) cure with a vacuum pressure. This method must be used for repairs on the
leading edge with damage larger than 2 inches in diameter.

51-11-11-20 Wet Layup Repair Maintenance Practices

The following repairs may be performed on any of the Raisbeck fiberglass components. The repair
size is limited to the ability to keep the component contours (except on the leading edge) where
damage is larger than 2 inches in diameter. The repairs can be round or rectangular with round
corners.

removed.
4. Wire brush and solvent clean.
5. Use the GTAW method and ER 347 filler metal, and weld to get complete penetration of the part.
A copper backing bar with a groove .06-.09 inch deep by a width approximately 1/8 inch wider
than the gap made by grinding will allow welding and minimize distortion and drop through.
6. Examine with dye penetrant to make sure there are no cracks or excessive weld porosity.
7. Grind as necessary to blend the weld into the structure.
8. Corrosion-Resistant Steel (CRES) may be polished for appearance purposes. If parts are
polished with 150-mesh of finer abrasives consisting of alumina (Ao203) or silicon carbide no
further passivation is required. Recommended buffing wheel speeds are 4,500-6,500 surface
feet per minute (SFM) for satin finishes and 7,000-9,000 SFM for gloss finishes. Lea compounds
(6-B-56 and 6-B-602) or equivalent are recommended abrasives. Do not use rouge compounds

61 Propellers
C90, E90 Series Propellers
61-00-10-00 Quiet Turbofan Propellers Description and Operation
Each engine is equipped with a Raisbeck/Hartzell Quiet Turbofan, four-blade, full feathering,
constant-speed, counterweighted, reversing, variable-pitch propeller mounted on the output shaft of
the reduction gear box. The propeller pitch and speed are controlled by engine oil pressure, through
single-action, engine-driven propeller governors. Centrifugal counterweights assisted by a feathering
spring, move the blades toward the low RPM (high pitch) position and into the feathered position.
Governor boosted engine oil pressure moves the propeller to the high RPM (low pitch) hydraulic stop
and reverse position. The propellers have no low RPM (high pitch) stops; this allows the blades to
feather after engine shut down. Low pitch propeller position is determined by a mechanically
monitored hydraulic stop. The propeller servo piston is connected by four spring-loaded sliding rods
to the slip ring mounted behind the propeller. Movement is transferred through the propeller
reversing lever to the Beta valve of the governor. When the propeller is rotating at a speed lower
than that selected on its governor, the governor pump provides oil pressure to the servo piston and
decreases the pitch of the propeller blades until the feedback of motion from the slip ring pulls the
Beta valve into position blocking the supply of oil to the propeller, thus preventing further pitch
changes. Throughout this and referenced Beechcraft documentation, the term "Constant Speed
Governor", “Propeller Governor" and "Primary Governor" are used interchangeably to refer to the
same mounted propeller speed control unit.

NOTE: During in-flight engine shut down, the feathered propeller may exhibit slight
rotation. Reference the applicable Pratt & Whitney Canada Maintenance
Manual for inspection and maintenance requirements for engine out,
propeller windmilling greater than 20 RPM and engine oil loss during in flight
engine shut down.
The Raisbeck/Hartzell Quiet Turbofan, four-bladed Propellers (HC-D4N-3C/D9290K) have a full
feathered angle of 84.5 degrees ±.5 degree at the 30-inch station, a mechanical reverse pitch stop of
-9.0 degrees ±.5 degree, and a low pitch stop of 20.1 degrees ±.1 degree.

should be within 1.8% of the value designated by the pressure altitude and temperature
conversion graph Chart A, for the ambient conditions under which the engine is operating.
Repeat this check on the other engine. The difference between torque-meter readings on the
engines should not exceed .9%. If the torque meter readings do not fall within the limitations
described by the graph, or if the difference between the LH and RH engines exceeds .9%, the
following adjustments are required:

CAUTION: HOLD STUDS WHEN TURNING BETA NUTS.

a) When the torque change required rig an engine within the design limits does not exceed
.9%, disconnect the fuel topping governor inner connecting rod, and disconnect the control
cable rear clevis from the Beta control cam. Adjust the clevis in or out until engine torque is
within the prescribed limits and the torque of each engine is the same, then reconnect the
inner connecting rod and the rear clevis.
b) When the torque change required to bring an engine within the prescribed limits exceeds
.9%, adjustment of the stop (Beta) nut on each of the four low pitch stop rods for the
propeller is required. All four nuts must be adjusted to an identical setting (see FIGURE 3).
One flat of rotation on the Beta nuts (clockwise to increase or counterclockwise to decrease)
changes engine torque approximately .7%. Adjust the Beta nuts as necessary to bring the

F90 Quiet Turbofan Propellers

61-00-20-00 Description and Operation
Each engine is equipped with a Raisbeck/Hartzell Quiet Turbofan, four-blade, full-feathering,
constant-speed, counterweighted, reversing, variable-pitch propeller mounted on the output shaft of
the reduction gearbox. The propeller pitch and speed are controlled by engine oil pressure, through
single-action, engine-driven propeller governors. Centrifugal counterweights, assisted by a feathering
spring, put the blades into the low RPM (high pitch) position and into the feathered position.
Governor-boosted engine oil pressure puts the propeller into the high RPM (low pitch) hydraulic stop,
and into the reverse position. The propellers have no low RPM (high pitch) stops; this allows the
blades to feather after the engine is shut down.

NOTE: During in-flight engine shut down, the feathered propeller may exhibit slight
rotation. Reference the applicable Pratt & Whitney Canada Maintenance
Manual for inspection and maintenance requirements for engine out,
propeller windmilling greater than 20 RPM and engine oil loss during in flight
engine shut down.
Reversing propeller-setting is changed to full feathered angle of 86 degrees at the 30-inch station and
mechanical reverse pitch stop of -10.5 degrees ±.5 degree. Low pitch propeller position is
determined by a hydraulic stop that is mechanically monitored. The propeller servo piston is
connected by four spring-loaded sliding rods to the slip ring. The slip ring is installed behind the
propeller. Motion is transferred through the propeller-reversing lever to the Beta valve of the
governor. The initial forward motion of the Beta valve blocks off the flow of oil to the propeller.
Further forward motion causes oil to flow from the propeller at a flow rate that is less than that
selected on the governor. The governor pump provides oil pressure to the servo piston and
decreases the pitch of the propeller blades until the feedback of motion from the slip ring pulls the
Beta valve into a position that stops the supply of oil to the propeller, thus preventing further pitch
changes.

61-00-20-05 Inspection

NOTE: If this test is not done in zero-wind conditions, take an average of the upwind
and downwind readings to get valid results.

With the propeller levers completely forward, advance the cockpit power lever for the engine until the
propeller reaches 1,800 RPM (1,700 RPM if equipped with PT6A-135A engines and rigged at 1,750
RPM). The torque meter reading for the engine must be +20/-0 lb-ft from the maximum value shown
by the pressure altitude and temperature conversion graphs, for the ambient conditions that the
engine is operating in. Do this test again for the other engine. The difference between torquemeter
readings on the engines should not exceed 20 lb-ft.
If the torque meter readings are not correct as shown in the graph, or if the difference between the
Left and Right engines exceeds 20 lb-ft, perform the adjustments given below:
Adjust the stop (Beta) nut on each of the four pitch stop rods for the propeller. All four nuts must be
adjusted to an identical position. One flat of rotation on the Beta nuts (clockwise to increase,
counterclockwise to decrease) changes engine torque approximately 20 lb-ft. Adjust the Beta nuts as
necessary to obtain engine operation within the prescribed limits. Do not use the Beta Valve for this
adjustment.

100/A100 Quiet Turbofan Propellers

61-00-30-00 Description and Operation
Each engine is equipped with a Raisbeck/Hartzell Quiet Turbofan, four-blade, full feathering,
constant-speed, counterweighted, reversing, variable-pitch propeller mounted on the output shaft of
the reduction gear box. The propeller pitch and speed are controlled by engine oil pressure, through
single-action engine-driven propeller governors. Centrifugal counterweights, assisted by a feathering
spring, move the blades toward the low RPM (high pitch) position and into the feathered position.
Governor boosted engine oil pressure moves the propeller to the high RPM (low pitch) hydraulic stop
and reverse position The propellers have no low RPM (high pitch) stops; this allows the blades to
feather after engine shut down.

NOTE: During in-flight engine shut down, the feathered propeller may exhibit slight
rotation. Reference the applicable Pratt & Whitney Canada Maintenance
Manual for inspection and maintenance requirements for engine out,
propeller windmilling greater than 20 RPM and engine oil loss during in flight
engine shut down.
Low pitch propeller position is determined by a mechanical monitored hydraulic stop. The propeller
servo piston is connected by four spring-loaded sliding rods to the slip ring mounted behind the
propeller. Movement is transferred through the propeller reversing lever to the Beta valve of the
governor. The initial forward motion of the Beta valve blocks off the flow of oil to the propeller.
Further motion forward dumps the oil from the propeller at a speed lower than that selected on the
governor. The governor pump provides oil pressure to the servo piston and decreases the pitch of
the propeller blades until the feedback of motion from the slip ring pulls the Beta valve into a position
blocking the supply of oil to the propeller, thus preventing further pitch changes. Throughout this and
referenced Beechcraft documentation, the term "Constant Speed Governor", "Propeller Governor",
and "Primary Governor" are used interchangeable to refer to the same engine mounted propeller
speed control unit.

Ground Run Power Symmetry and Low Pitch Torque Check
Reference TORQUE CHART A
If this test is not done in zero-wind conditions, take an average of the upwind and downwind readings
to get valid results.
With the propeller levers fully forward, advance the cockpit power lever until the propeller reaches
1,800 RPM. The torque meter reading for the engine should within 40 lb-ft of the value specified by
the pressure altitude and temperature conversion chart (+20/-0 lb-ft).
Repeat this test on the other engine. The difference between the torque meter readings on the
engines should not exceed 20 lb-ft. If the torque meter readings do not fall within the limitations
described above, or the difference between the engines exceeds 20 lb-ft, make the adjustments given
below:
Adjust the stop (Beta) nut on each of the four pitch stop rods for the propeller. All four nuts must be
adjusted to an identical setting. One flat of rotation on the Beta nuts (clockwise to increase;
counterclockwise to decrease) changes engine torque approximately 20 lb-ft. Adjust the Beta nuts as
necessary to bring the engine within the prescribed limits.

61-00-40-00 Quiet Turbofan Propellers Description and Operation

Each engine is equipped with a Raisbeck/Hartzell Quiet Turbofan, four-blade, full-feathering,
constant-speed, counterweighted, reversing, variable-pitch propeller mounted on the output shaft of
the reduction gear box. The propeller pitch and speed are controlled by engine oil pressure, through
single-action, engine-driven propeller governors. Centrifugal counterweights, assisted by a feathering
spring, move the blades toward the low RPM (high pitch) position and into the feathered position.
Governor boosted engine oil pressure moves the propeller to the high RPM (low pitch) hydraulic stop
and reverse position. The propellers have no low RPM (high pitch) stops; this allows the blades to
feather after engine shut down.

NOTE: During in-flight engine shut down, the feathered propeller may exhibit slight
rotation. Reference the applicable Pratt & Whitney Canada Maintenance
Manual for inspection and maintenance requirements for engine out,
propeller windmilling greater than 20 RPM and engine oil loss during in flight
engine shut down.

The Raisbeck/Hartzell Quiet Turbofan, four-blade propellers (HC-D4N-3A/D9383K) have a full

feathered angle of 86 degrees at the 30-inch station and mechanical reverse pitch stop of -10.5
degrees ±.5 degree.

61-00-41-00 Swept Turbofan Propellers Description and Operation

Each engine is equipped with a Raisbeck/Hartzell Swept Turbofan, four-blade, full-feathering,
constant-speed, counterweighted, reversing, variable-pitch propeller mounted on the output shaft of
the reduction gear box. The propeller pitch and speed are controlled by engine oil pressure, through
single-action, engine-driven propeller governors. Centrifugal counterweights, assisted by a feathering
spring, move the blades toward the low RPM (high pitch) position and into the feathered position.
Governor boosted engine oil pressure moves the propeller to the high RPM (low pitch) hydraulic stop
and reverse position. The propellers have no low RPM (high pitch) stops; this allows the blades to

Ground Run Power Symmetry and Low Pitch Torque Check

CAUTION: STABILIZED GROUND OPERATION WITHIN THE PROPELLER

RESTRICTED RPM RANGE CAN GENERATE HIGH PROPELLER
STRESSES AND RESULT IN FATIGUE DAMAGE TO THE
PROPELLER. THIS DAMAGE CAN LEAD TO A REDUCED
PROPELLER FATIGUE LIFE, PROPELLER FAILURE, AND LOSS OF
CONTROL OF THE AIRPLANE. THE PROPELLER RESTRICTED RPM
RANGE IS DEFINED IN THE AIRPLANE FLIGHT MANUAL. CONTACT
HARTZELL PROPELLER FOR CORRECTIVE ACTIONS IF A
PROPELLER RESTRICTION OR LIMITATION IS VIOLATED.
RESTRICTED RANGE IS CONTINUOUS OPERATION BETWEEN 400
AND 1,150 PROPELLER RPM.

CAUTION: OBSERVE STANDARD FIRE AND PROPELLER SAFETY

PRECAUTIONS. MAKE SURE RAMP IS CLEAR BEFORE STARTING
ENGINES.

Refer to the appropriate sections of the Beechcraft Super King Air Pilot’s Operating Handbook and
start engines. Accomplish the checks and adjustments as follows:
Torque Chart A for models 200 and B200.
Torque Chart B for model A200, serial numbers BC-1 and after, BD-1 and after, BP-1, BP-19 thru
BP-22, and BP-24 and after.

NOTE: If this check is not being performed under zero wind conditions, take an
average of the upwind and downwind readings to obtain valid results.

With the propeller levers fully forward, advance the cockpit power lever for the engine until the
propeller reaches 1,800 RPM. The torque meter reading for the engine must not exceed and should
be within 40 lb-ft of the value designated by the pressure altitude and temperature conversion graph
CHART A, or must not exceed and should be within 1.8% of the value designated by the pressure
altitude and temperature conversion graph CHART B, for the ambient conditions under which the
engine is operating. Repeat this check on the other engine. The difference between torque-meter
readings on the engines should not exceed 20 lb-ft (CHART A), or .9% (CHART B). If the torque
meter readings do not fall within the limitations described by the graph or if the difference between the
LH and RH engines exceeds 20 lb-ft (CHART A), or .9% (CHART B), the following adjustments are
required:
When the torque change required to bring an engine within the design limits does not exceed 20 lb-ft
(CHART A), or .9% (CHART B), disconnect the fuel topping governor inner connecting rod and
disconnect the control cable rear clevis from the Beta control cam. Adjust the clevis in or out until
engine torque is within the prescribed limits and the torque of each engine is the same, then
reconnect the inner connecting rod and the rear clevis.
When the torque change required to bring an engine within the prescribed limits exceeds 20 lb-ft
(CHART A), or .9% (CHART B), adjustment of the stop (Beta) nut on each of the four low pitch stop
rods for the propeller is required. All four nuts must be adjusted to an identical setting. One flat of
rotation on the Beta nuts (clockwise to increase or counterclockwise to decrease) changes engine
torque approximately 15 lb-ft (CHART A), or .7% (CHART B). Adjust the Beta nuts as necessary to
bring the engine within the prescribed limits.

Low Idle Adjustment

Set the condition lever at LOW IDLE and the power level at IDLE. Adjust N1 to achieve a propeller
speed of 1,150 RPM +50/-0 RPM. Perform adjustment per Beechcraft Super King Air 200 Series
Maintenance Manual, Chapter 76.
Constant Speed Governor Adjustment
Perform a functional test of the Constant Speed Governors per Beechcraft Super King Air 200 Series
Maintenance Manual, Chapter 61.
Overspeed Governor Operational Test
Perform an operational test of the Overspeed Governor per Beechcraft Super King Air 200 Series
Maintenance Manual, Chapter 61.
Feathering Adjustment
Adjust autofeather power switch as required per Beechcraft Super King Air 200 Series Maintenance
Manual, Chapter 61.

CAUTION: CONTINUOUS OPERATION BETWEEN 400 AND 1,150 RPM MAY

CAUSE DAMAGE TO PROPELLER.

NOTE: If ground check of the autofeather system is unsatisfactory, the problem may
be that the low pitch stops (propeller blade angles) are too coarse. In this
case, reset the low pitch stops so that the minimum torque value allowed at
1,800 RPM is utilized. This will require lowering low idle (N1) to reduce
propeller idle to 1,150 RPM, reducing torque at low idle.

NOTE: Concerning early model 200 aircraft, serial numbers BB-2 thru BB-733, BB-
735 thru BB-792, BB-794 thru BB-828, BB-830 thru BB-853, BB-871 thru
BB-873, BB-892, BB-893, BB-912, BL-1 thru BL-36, BN-1, and BT-1 thru BT-
22: If ground check of the autofeather system is unsatisfactory, the problem
may be due to the higher oil pressure associated with the four-bladed
propeller tripping the pressure switch prematurely. Raisbeck Engineering
Service Bulletin SB-06-02 provides for replacement of the stock pressure
switch with an approved alternate pressure switch with a higher tripping
pressure.

Low Idle Check

CAUTION: STABILIZED GROUND OPERATION BETWEEN 400 AND 1,150 RPM

IS PROHIBITED.

Set the condition lever at low idle and the power level at idle. Adjust low idle in accordance with the
applicable King Air 200 Series Maintenance Manual to achieve N2 (propeller RPM) of 1,150 +50/-0
RPM.
High Idle Check
Adjust high idle in accordance with the applicable Beechcraft King Air 200 Series Maintenance
Manual.
Fuel Cutoff Lever Adjustment
Adjust in accordance with the applicable Beechcraft King Air 200 Series Maintenance Manual.
Propeller Autofeathering System Check

CAUTION: STABILIZED GROUND OPERATION BETWEEN 400 AND 1,150 RPM

IS PROHIBITED.

Check and adjust autofeather power switch in accordance with the applicable Beechcraft King Air 200
Series Maintenance Manual.

NOTE: If ground check of the autofeather system is unsatisfactory, the problem may
be that the low pitch stops (propeller blade angles) are too coarse. In this
case, reset the low pitch stops so that the minimum torque value allowed at
1,800 RPM is utilized. This will require lowering low idle N1 to reduce
propeller idle (N2) RPM to 1,150, reducing torque at low idle.

NOTE: Concerning early Model 200 aircraft, serial numbers BB-2 thru BB-733, BB-
735 thru BB-792, BB-794 thru BB-828, BB-830 thru BB-853, BB-871 thru BB-
873, BB-892, BB-893, BB-912, BL-1 thru BL-36, BN-1, and BT1 thru BT-22:
If ground check of the autofeather system is unsatisfactory, the problem may
be due to the higher oil pressure associated with the four-bladed propeller
tripping the pressure switch prematurely. Raisbeck Engineering Service
Bulletin No. 06-02 provides for replacement of the stock pressure switch with
an approved alternate pressure switch with a higher tripping pressure.
Governor Operational Check
Check the operation in accordance with the applicable Beechcraft King Air 200 Series Maintenance
Manual.

Super King Air 300/300LW, B300/B300C Propellers

61-00-51-00 Four-Blade Swept Turbofan Propellers Description and
Operation
Each engine is equipped with a Raisbeck/Hartzell Swept Turbofan, four-blade, full-feathering,
constant-speed, counterweighted, reversing, variable-pitch propeller mounted on the output shaft of
the reduction gear box. The propeller pitch and speed are controlled by engine oil pressure, through
single-action, engine-driven propeller governors. Centrifugal counterweights, assisted by a feathering
spring, move the blades toward the low RPM (high pitch) position and into the feathered position.
Governor boosted engine oil pressure moves the propeller to the high RPM (low pitch) hydraulic stop
and reverse position. The propellers have no low RPM (high pitch) stops; this allows the blades to
feather after engine shut down.

NOTE: During in-flight engine shut down, the feathered propeller may exhibit slight
rotation. Reference the applicable Pratt & Whitney Canada Maintenance
Manual for inspection and maintenance requirements for engine out,
propeller windmilling greater than 20 RPM and engine oil loss during in flight
engine shut down.
The Raisbeck/Hartzell Four-Blade Swept Turbofan Propellers (HC-E4P-3K/E10479SK) have a full
feathered angle of 78.0 degrees ±.5 degree at the 42-inch station, a mechanical reverse pitch stop of
-14.0 degrees ±.5 degree, and a low pitch stop of 17.1 degrees ±.1 degree.

Low Idle Check

The following steps set N1 (Gas Generator RPM) and N2 (Propeller RPM) at idle.

CAUTION: STABILIZED GROUND OPERATION BETWEEN 400 AND 1,050

PROPELLER RPM IS PROHIBITED. OPERATION BETWEEN 0 AND
400 PROPELLER RPM IS PERMISSIBLE ONLY WITH PROPELLER
FEATHERED.

WARNING: STABILIZED GROUND OPERATION WITHIN THE PROPELLER

RESTRICTED RPM RANGE CAN GENERATE HIGH PROPELLER
STRESSES AND RESULT IN FATIGUE DAMAGE TO THE
PROPELLER AND RESULT IN PROPELLER FAILURE AND LOSS OF
CONTROL OF THE AIRCRAFT.

1. Position Power Lever against the IDLE detent.

2. Position Condition Lever in the LOW IDLE position.
N1 should be between 62% - 65% in this configuration. Adjust as need as follows.
a. Loosen Fuel Control Unit (FCU) lever clamp screw.
b. To increase N 1 loosen upper idle adjustment screw and tighten the lower adjustment
screw equally.
To decrease N1, loosen lower idle adjustment screw and tighten the upper idle adjustment screw
equally.
One-sixth of a turn of each screw equals approximately 3.5% change in N1.
c. Tighten FCU lever clamp screw.
3. With N 1 set at 62%, N 2 should be1,050 +50/-0 RPM. Adjust Ground Idle Solenoid as
necessary to set N 2 to 1,050 +50/-0 RPM.
a. Loosen bolts on Ground Idle Solenoid Bracket securing solenoid. Do not loosen bolts
securing bracket to the Reversing Cable.
To increase N2, move Ground Idle Solenoid aft. This will increase pull on Beta Valve when
solenoid is energized, flattening the blade angle.
To decrease N2, move Ground Idle Solenoid forward. This will decrease pull on Beta Valve when
solenoid is energized, resulting in a coarser blade angle.
b. Tighten bolts securing the Ground Idle Solenoid.
4. Adjust taxi speed characteristics as follows.
a. Observing N1 and N2 limitations, adjust Beta Valve Ground Fine Solenoid pull and N 1
Low Idle in concert to tailor taxi characteristics.
Decreasing pull on the Beta Valve and increasing N1 will result in a faster taxi speed.
Increasing pull on the Beta Valve and decreasing N1 will result in a slower taxi speed.

2. Adjust N 1 by turning Reverse Stop Screw in to increase RPM or out to decrease RPM. One
half turn equals approximately 2.7% N 1 .
When moving Power Lever through ground fine, observe that N2 rises. If there is a slight
decrease in N2 just before going into the reverse detent, it indicates that the propellers are going
into reverse too soon. Adjust as necessary.
a. Measure and record Beta Valve Depth.
b. Remove aft Beta Clevis from Reversing Cam and reinstall it one hole lower than its
original position.
c. Adjust the Rear Clevis to obtain the Beta Valve Depth recorded in Step a. The Torque

Propeller Synchrophaser Functional Check

1. Start engines and place propeller levers in the HIGH IDLE position. Increase N 2 to 1,700
RPM on both propellers.
2. Retard the propellers levers to reduce N 2 to 1,500 RPM on both propellers.

CAUTION: DO NOT EXCEED TORQUE LIMITATIONS.

3. Turn synchrophaser to the ON position.

4. Using the propeller lever, increase N 2 of the left propeller slightly and verify that the
synchrophaser system increased N 2 of the right propeller to match.
5. If this check is not satisfactory, turn the synchrophaser off and repeat Steps 1 thru 4 to
confirm result. Continue to Step 5 if result is satisfactory.
6. Continue increasing N 2 with the propeller lever until synchronization is lost and record that
RPM.
7. Using the propeller lever, slowly decrease N 2 on the left engine below that of the right
engine until synchronization is lost and record that RPM.
8. The difference between the RPM recorded in Steps 5 and 6, where synchronization was
lost should be at least 23 to 27 RPM. Satisfactory results indicate the right propeller
governor is responding to commands from the control box and the control box is functioning
properly. If the Synchrophaser Functional Check was not satisfactory, perform the
Continuity.
Continuity Check
1. Turn the Battery Master Switch OFF and open the Synchrophaser Circuit Breaker.
2. Remove the connector from the Control Box.
3. Reference FIGURE 1 and verify connector plug configuration.
4. Perform continuity checks indicated in TABLE 1 thru 3.

NOTE: Readings in TABLES 1 thru 3 may be as much as 20% higher during heat
soak, after engine shut-down.

5. After continuity checks, close the Synchrophaser Circuit Breaker and turn the Battery
Master Switch ON. Check for voltage between pins A and B. Turn Battery Master Switch
OFF and open Synchrophaser Circuit Breaker.

CAUTION: DO NOT CONNECT THE CONNECTOR PLUG TO THE CONTROL

BOX BEFORE TURNING BATTERY MASTER SWITCH OFF AND
OPENING SYNCHROPHASER CIRCUIT BREAKER.

6. Correct and wiring discrepancies revealed in Steps 1 thru 5. Replace any component that
failed the resistance checks as specified in CHART 1 thru 3 and repeat Steps 1 thru 5 to
verify no discrepancies remain.
7. If no faults were found, restore the Synchronization System and perform the Governor
Operational Check.

Governor Operational Check

1. Connect breakout box between plug P151 of the aircraft wiring harness and Synchrophaser
Control Box (P/N 2136696 or 213765).

NOTE: Breakout Box T18BC-61-000-1 may be fabricated referencing FIGURE 2.

2. Start engines and set the propeller levers in HIGH. Increase N 2 to 1,700 RPM.
3. Using the propeller levers, reduce N 2 to 1,500 RPM to verify the propellers are being
controlled by the governors.

CAUTION: DO NOT EXCEED TORQUE LIMITATIONS.

4. Install a jumper between pins R and A. Close the control switch. N 2 of the right propeller
should increase.
5. Open the control switch and remove the jumper.
6. Install a jumper between pins L and A. Close the control switch. N 2 of the left propeller
should increase.
7. Open the control switch and remove the jumper.
Failure of either governor indicates:
a. No voltage from the control box (pins K and J).
b. Fault in the governor.
8. If there is no N 2 increase in Step 4 or 6, check resistance between pins B and J or B and K
of the Control Box. There should be approximately 800 ohm of resistance. This indicates
that the 3.9 ohm resistor is functional. Some Control Boxes have an automatic resetting
resistor that will reset when power is removed from the Control Box.

Pick-Up Output Check

In order to check the Pick-Up voltage output, an oscilloscope is needed to display the output
waveform and measure peak to peak voltages. Reference FIGURE 3.
1. Turn the Battery Master Switch OFF and open the Synchrophaser Circuit Breaker.
2. Disconnect the connector plug from the Control Box.
3. Connect the oscilloscope:
4. Between pins D and E, left Pick-Up.
5. Between pins C and G, right Pick-Up.
6. Start the engines and adjust N 2 to 1,700 RPM.

CAUTION: DO NOT EXCEED TORQUE LIMITATIONS.

7. Observe the wave form generated by the Pick-Ups. The wave forms should depart and rise
smoothly from the baseline to positive peak, drop off to negative peak, and return smoothly
to baseline. The ascending and descending sides of the peaks should be symmetrical, with
no secondary peaks. Reference FIGURE 6 for waveform and fault diagnostics.
8. Record peak to peak voltage of the left and right Pick-Ups. The output voltage should be
between 2 and 4 volts.
9. Adjust the gap between the Targets and Pick-Ups to obtain matching output voltage
between the left and right Pick-Ups. The output voltage should match to within .5 volt,
necessary to maintain the 1 volt variation from left to right for proper Control Box function.
Moving the Pick-Up away from the Target will decrease output voltage.
Moving the Pick-Up towards the Target will increase the output voltage.
.007 inch adjustment equals approximately .5 volt.
10. After final adjustment, torque the Pick-Up locknuts to a maximum of 25 lb-in and secure
with lockwire.
Ensure the Battery Master Switch is OFF and the Synchrophaser Circuit Breaker is open before
reconnecting the connector plug to the Control Box.

61-00-52-00 Five-Blade Swept Turbofan Propellers Description and

Operation
Each engine is equipped with a Raisbeck/Hartzell Five-Blade Swept Turbofan, full-feathering,
constant-speed, counterweighted, reversing, variable-pitch propeller mounted on the output shaft of
the reduction gear box. The propeller pitch and speed are controlled by engine oil pressure, through
single-action, engine-driven propeller governors. Centrifugal counterweights, assisted by a feathering
spring, move the blades toward the low RPM (high pitch) position and into the feathered position.
Governor boosted engine oil pressure moves the propeller to the high RPM (low pitch) hydraulic stop
and reverse position. The propellers have no low RPM (high pitch) stops; this allows the blades to
feather after engine shut down.

Low Idle Check

The following steps set N1 (Gas Generator RPM) and N2 (Propeller RPM) at idle.

CAUTION: STABILIZED GROUND OPERATION BETWEEN 400 AND 1,050 RPM

IS PROHIBITED. OPERATION BETWEEN 0 AND 400 PROPELLER
RPM IS PERMISSIBLE ONLY WITH PROPELLER FEATHERED.

WARNING: STABILIZED GROUND OPERATION WITHIN THE PROPELLER

RESTRICTED RPM RANGE CAN GENERATE HIGH PROPELLER
STRESSES AND RESULT IN PROPELLER FAILURE AND LOSS OF
CONTROL OF THE AIRCRAFT.

1. Position Power Lever against the IDLE detent.

2. Position Condition Lever in the LOW IDLE position.
N1 should be between 62% - 65% in this configuration. Adjust as needed as follows.
a. Loosen Fuel Control Unit (FCU) lever clamp screw.
b. To increase N 1 , loosen upper idle adjustment screw and tighten the lower idle
adjustment screw equally.
To decrease N1, loosen lower idle adjustment screw and tighten the upper idle adjustment screw
equally. One-sixth of a turn of each screw equals approximately 3.5% change in N1.
c. Tighten FCU lever clamp screw.
3. With N 1 set at 62% - 65%, N 2 should be 1,050 +50/-0 RPM. Adjust Ground Idle Solenoid as
necessary to set N 2 to 1,050 +50/-0 RPM.
a. Loosen bolts on Ground Idle Solenoid Bracket securing solenoid. Do not loosen bolts
securing bracket to the Reversing Cable.
To increase N2, move Ground Idle Solenoid aft. This will increase pull on Beta Valve when
solenoid is energized, flattening the blade angle.
To decrease N2, move Ground Idle Solenoid forward. This will decrease pull on Beta Valve when
solenoid is energized, resulting in a coarser blade angle.
4. Adjust taxi speed characteristics as follows:
a. Observing N1 and N2 limitations, adjust Beta Valve Ground Fine Solenoid pull and N 1
Low Idle in concert to tailor taxi characteristics.
Decreasing pull on the Beta Valve and increasing N1 will result in a faster taxi speed.
Increasing pull on the Beta Valve and decreasing N1 will result in a slower taxi speed.

Propeller Synchrophaser Functional Check

1. Start engines and place propeller levers in the HIGH IDLE position. Increase N 2 to 1,700
RPM on both propellers.
2. Retard the propellers levers to reduce N 2 to 1,500 RPM on both propellers.

CAUTION: DO NOT EXCEED TORQUE LIMITATIONS.

3. Turn synchrophaser to the ON position.

4. Using the propeller lever, increase N 2 of the left propeller slightly and verify that the
synchrophaser system increased N 2 of the right propeller to match.
If this check is not satisfactory, turn the synchrophaser off and repeat Steps 1 thru 4 to confirm result.
Continue to Step 5 if result is satisfactory.
5. Continue increasing N 2 with the propeller lever until synchronization is lost and record that
RPM.
6. Using the propeller lever, slowly decrease N 2 on the left engine below that of the right
engine until synchronization is lost and record that RPM.
The difference between the RPM recorded in Steps 5 and 6, where synchronization was lost should
be at least 23 to 27 RPM. Satisfactory results indicate the right propeller governor is responding to
commands from the control box and the control box is functioning properly. If the Synchrophaser
Functional Check was not satisfactory, perform the Continuity Check.
Continuity Check
1. Turn the Battery Master Switch OFF and open the Synchrophaser Circuit Breaker.
2. Remove the connector from the Control Box.
3. Reference FIGURE 1 and verify connector plug configuration.
4. Perform continuity checks indicated in TABLE 1 thru 3.

NOTE: Readings in TABLES may be as much as 20% higher during heat soak, after
engine shut-down.

5. After continuity checks, close the Synchrophaser Circuit Breaker and turn the Battery
Master Switch ON. Check for voltage between pins A and B. Turn Battery Master Switch
OFF and open Synchrophaser Circuit Breaker.

CAUTION: DO NOT CONNECT THE CONNECTOR PLUG TO THE CONTROL BOX

BEFORE TURNING BATTERY MASTER SWITCH OFF AND OPENING
SYNCHROPHASER CIRCUIT BREAKER.

6. Correct and wiring discrepancies revealed in Steps 1 thru 5. Replace any component that
failed the resistance checks as specified in TABLE 1 thru 3 and repeat Steps 1 thru 5 to
verify no discrepancies remain.
7. If no faults were found, restore the Synchronization System and perform the Governor
Operational Check.

Governor Operational Check

1. Connect Breakout Box between plug P151 of the aircraft wiring harness and
Synchrophaser Control Box (P/N 2136696 or 213765).

NOTE: Breakout Box may be fabricated referencing FIGURE 2.

2. Start engines and set the propeller levers in HIGH. Increase N 2 to 1,700 RPM.
3. Using the propeller levers, reduce N 2 to 1,500 RPM to verify the propellers are being
controlled by the governors.

CAUTION: DO NOT EXCEED TORQUE LIMITATIONS.

4. Install a jumper between pins R and A. Close the control switch. N 2 of the right propeller
should increase.
5. Open the control switch and remove the jumper.
6. Install a jumper between pins L and A. Close the control switch. N 2 of the left propeller
should increase.
7. Open the control switch and remove the jumper.
Failure of either governor indicates:
a. No voltage from the control box (pins K and J).
b. Fault in the governor.
8. If there is no N 2 increase in Step 4 or 6, check resistance between pins B and J or B and K
of the Control Box. There should be approximately 800 ohm of resistance. This indicates
that the 3.9 ohm resistor is functional. Some Control Boxes have an automatic resetting
resistor that will reset when power is removed from the Control Box.
9. If no faults were found, perform the Pick-Up Output Check.

b. Between pins C and G, right Pick-Up.
4. Start the engines and adjust N 2 to 1,700 RPM.

CAUTION: DO NOT EXCEED TORQUE LIMITATIONS.

5. Observe the wave form generated by the Pick-Ups. The wave forms should depart and rise
smoothly from the baseline to positive peak, drop off to negative peak, and return smoothly
to baseline. The ascending and descending sides of the peaks should be symmetrical, with
no secondary peaks. Reference FIGURE 3 for waveform and fault diagnostics.
6. Record peak to peak voltage of the left and right Pick-Ups. The output voltage should be
between 2 and 4 volts.
7. Adjust the gap between the Targets and Pick-Ups to obtain matching output voltage
between the left and right Pick-Ups. The output voltage should match to within .5 volt,
necessary to maintain the 1 volt variation from left to right for proper Control Box function.
Moving the Pick-Up away from the Target will decrease output voltage.
Moving the Pick-Up towards the Target will increase the output voltage.
.007 inch adjustment equals approximately .5 volt.
8. After final adjustment, torque the Pick-Up locknuts to a maximum of 25 lb-in and secure
with lockwire.
9. Ensure the Battery Master Switch is OFF and the Synchrophaser Circuit Breaker is open
before reconnecting the connector plug to the Control Box.
