INTRODUCTION

The contents of this document are applicable to the certified SAAB 340 airliner versions SAAB SF 340A (same
as SAAB–FAIRCHILD 340A) and SAAB 340B.
If some deviations from the type certificated configuration and equipment required by the operating rules were
not permitted, the aircraft could not be flown unless all such equipment was operable. Experience has proven
that the operation of every system or component installed on the aircraft is not necessary when the remaining
operative instruments and equipment provide continued safe operations. Therefore, certain deviations from these
requirements are authorized to permit continued or uninterrupted operation of the aircraft. A MASTER MINIMUM
EQUIPMENT LIST (MMEL) provide operators with the authority to operate an aircraft with certain items of
components inoperative and provides for an acceptable level of safety maintained by appropriate operations
limitations, by a transfer of the function to another operating component, or by reference to other instruments or
components providing the required information.
The MMEL does not include obviously required items such as wings, rudders, flaps, engines, landing gear, etc.
Also, The list may not include items which do not affect the airworthiness of the aircraft, such as galley equipment,
entertainment systems etc. However, it is important to note that ALL ITEMS WHICH ARE RELATED TO THE
AIRWORTHINESS OF THE AIRCRAFT AND NOT INCLUDED ON THE LIST ARE AUTOMATICALLY
REQUIRED TO BE OPERATIVE.
Unless otherwise specified in the remarks column, it is not defined ”where” or ”when” an inoperative item is to
be repaired or replaced; but rather indicates through approval of MMELs those instruments and items of
equipment that may be inoperative for certain flight conditions with the intent that no flight can take off from an
airport with inoperative equipment other than that specified. The failure of instruments or items of equipment in
excess of those allowed to be inoperative by the MMEL causes the aircraft to be unairworthy. No distinction in
the MMEL is made for dispatch or operation of a flight between points of origin and termination including
intermediate stops of flights beyond the scheduled termination of the flight.
The MMEL was never intended to provide for continued operation of the aircraft for an indefinite period with
inoperative items. The basic purpose of the MMEL is to permit the operation of an aircraft with inoperative
equipment within the framework of a controlled and sound program of repairs and parts replacement. It is
important that the operator makes repairs at the first airport where repairs or replacements may be made but,
in any case, repair should be accomplished at the terminating airport, since additional malfunctions may require
the aircraft to be taken out of service.
Operators are responsible to verify that the failure in question really affects the system that is handled as an MMEL
item.
Operators are responsible for exercising the necessary operational control to assure that no aircraft is dispatched
or flown with multiple MMEL items inoperative without first determining that any interface or interrelationship
between inoperative systems or components will not result in a degradation in the level of safety and/or an undue
increase in crew workload.
The exposure to additional failures during continued operation with inoperative systems or components must also
be considered in determining that an acceptable level of safety is being maintained. The MMEL may not deviate
from requirements of the AFM limitations section, emergency procedures, or airworthiness directive unless the
AFM or airworthiness directive provide otherwise.
The MMEL does not include requirements laid down in national regulations (see Note (5) E).
The MMEL is intended to facilitate operators preparation of a MINIMUM EQUIPMENT LIST (MEL) for operations
according to applicable regulations.

Master Minimum Equipment List

DEFINITIONS
1. System & Sequence numbers (Column 1) are based on the Air Transport Association (ATA) Specification
Number 100.
A. ”Item” (Column 2) means the equipment, system, component, or function listed in the ”Item” column.
B. ”Category” (Column 3) Repair time Intervals: All users of this MMEL must effect repairs of inoperative
systems or components, deferred in accordance with the MMEL, at or prior to the repair times
established by the following letter designators:
(1) Where the MMEL shows a ”–” symbol in the category column, the MEL must reflect the actual
repair time Interval approved by the national aviation authorities.
(2) A ”blank space” in the category column means that this item is not subject for any repair time
interval. These items are normally those related to passenger convenience, comfort or
entertainment.
(3) Category A. Items in this category shall be repaired within the time interval specified in the remarks
column of the operator’s approved MEL.
(4) Category B. Items in this category shall be repaired within three (3) consecutive calendar days
(72 hours), excluding the day the malfunction was recorded in the aircraft maintenance
record/logbook. For example, if it were recorded at 10 a.m. on January 26th, the three day interval
would begin at midnight the 26th and end at midnight the 29th.
(5) Category C. Items in this category shall be repaired within ten (10) consecutive calendar days (240
hours), excluding the day the malfunction was recorded in the aircraft maintenance
record/logbook. For example, if it were recorded at 10 a.m. on January 26th, the 10 day interval
would begin at midnight the 26th and end at midnight February 5th.
(6) Category D. Items in this category shall be repaired within one hundred and twenty (120)
consecutive calendar days (2880 hours), excluding the day the malfunction was recorded in the
aircraft maintenance record/logbook.
The letter designators are listed in the ”Category” column (Column 3).
”Day of Discovery” is the calendar day an equipment/instrument malfunction was recorded in the
aircraft maintenance log and or record. This day is excluded from the calendar days or flight days
specified in the MMEL for the repair of an inoperative item of equipment. This provision is
applicable to all MMEL items, i.e. categories ”A, B, C and D”.
C. ”Number Installed” (Column 4) is the number (quantity) of items normally installed in the aircraft. This
number represents the aircraft configuration considered in developing this MMEL. Should the number
be a variable (e.g., passenger cabin items) a number is not required.
NOTE: Where the MMEL shows a variable number installed, the MEL must reflect the actual number
installed or an alternate means of configuration control approved by the national aviation
authorities.
D. ”Number Required for Dispatch” (Column 5) is the minimum number (quantity) of items required for
operation provided the conditions specified in Column 6 are met.
NOTE: Where the MMEL shows a variable number required for dispatch, the MEL must reflect the
actual number required for dispatch or an alternate means of configuration control approved
by the national aviation authorities.
E. ”Remarks or Exceptions” (Column 6) in this column includes a statement either prohibiting or permitting
operation with a specific number of items inoperative, provisos (conditions and limitations) for such
operation, and appropriate notes. If reference also is made to national aviation regulations the most
stringent requirement applies.
F. A vertical bar (change bar) in the left margin indicates a change, addition or deletion in the adjacent text
for the current revision of that page only. The change bar is dropped at the next revision of that page.

2. ”Airplane Flight Manual” (AFM) is the document required for type certification and approved by the applicable
responsible airworthiness authorities. The approved AFM for the specific aircraft is listed on the applicable
Type Certificate Data Sheet.
3. ”As required by National Aviation Regulations” means that the listed item may be subject to certain provisions
(restrictive or permissive) expressed in the individual operators national aviation regulations operating rules.
The number of items required by the national aviation regulations must be operative. Items installed that
are in excess of the national aviation regulations requirements may be permitted by the operator’s MEL to
be inoperative if not otherwise required by the MMEL.
4. ”
” Symbol in Column 6 indicates the listed item if inoperative, must be placarded to inform and remind the
crewmembers and maintenance personnel of the equipment condition.
NOTE: To the extent practical, placards should be located adjacent to the control or indicator for the item
affected; however, unless otherwise specified, placard wording and location will be determined by
the operator.
5. ”–” Symbol in Column 4 and/or Column 5 indicates a variable number (quantity) of the item installed.
NOTE: Where the MMEL shows a variable number installed, the MEL must reflect the actual number
installed or an alternate means of configuration control approved by the national aviation
authorities.
6. ”National Aviation Regulations” (NAR) means the applicable portions of the individual operators national
aviation regulations (such as FAR, JAR etc.).
7. ”Flight Day” means a 24 hour period (from midnight to midnight) either Universal Coordinated Time (UCT)
or local time, as established by the operator, during which at least one flight is initiated for the affected aircraft.
8. ”Icing Conditions” exist when visible moisture in any form is present (such as clouds, fog with visibility of one
mile or less, rain, snow, sleet, ice crystals) or standing water, slush, or snow (hard packed snow excluded)
is present on the ramps, taxiways or runways and the OAT or SAT is +5
C and below during ground and

9. Alphabetical symbol in Column 6 indicates a proviso (condition or limitation) that must be complied with for
operation with the listed item inoperative.
10. ”Inoperative” means a system and/or component malfunction to the extent that it does not accomplish its
intended purpose and/or is not consistently functioning normally within its approved operating limit(s) or
tolerance(s).
11. ”Indication” may be a digital display, or analog or digital readout on a cathode ray tube. Does not include
message.
12. ”Notes:” in Column 6 provides additional information for crewmember or maintenance consideration. Notes
are used to identify applicable material which is intended to assist with compliance, but do not relieve the
operator of the responsibility for compliance with all applicable requirements. Notes are not a part of the
provisos.
13. Inoperative components of an inoperative system: Inoperative items which are components of a system
which is inoperative are usually considered components directly associated with and having no other
function than to support that system. (Warning/caution systems associated with the inoperative system
must be operative unless relief is specifically authorized per the MMEL).
14. ”(M)” symbol indicates a requirement for a specific maintenance procedure which must be accomplished
prior to operation with the listed item inoperative. Normally these procedures are accomplished by
maintenance personnel; however, other personnel may be qualified and authorized to perform certain
functions. Procedures requiring specialized knowledge or skill, or requiring the use of tools or test equipment
should be accomplished by maintenance personnel. The satisfactory accomplishment of all maintenance
procedures, regardless of who performs them, is the responsibility of the operator. Appropriate procedures
are required to be published as part of the operator’s manual or MEL.
NOTE: The (M) and (O) symbols are required in the operator’s MEL unless otherwise authorized by the
national aviation authorities.

15. ”(O)” symbol indicates a requirement for a specific operations procedure which must be accomplished in
planning for and/or operating with the listed item inoperative. Normally these procedures are accomplished
by the flight crew; however, other personnel may be qualified and authorized to perform certain functions.
The satisfactory accomplishment of all procedures, regardless of who performs them, is the responsibility
of the operator. Appropriate procedures are required to be published as a part of the operator’s manual or
MEL.
NOTE: The (M) and (O) symbols are required in the operator’s MEL unless otherwise authorized by the
national aviation authorities.
16. ”Deactivated” and ”Secured” means that the specified component must be put into an acceptable condition
for safe flight. An acceptable method of securing or deactivating will be established by the operator.
17. ”Visual Flight Rules” (VFR) is as defined in national aviation regulations (such as FAR Part 91 etc.). This
precludes a pilot from filing an Instrument Flight Rules (IFR) flight plan.
18. ”Visual Meteorological Conditions” (VMC) means the atmospheric environment is such that would allow a
flight to proceed under the visual flight rules applicable to the flight. This does not preclude operating under
Instrument Flight Rules.
19. ”Visible Moisture” means an atmospheric environment containing water in any form that can be seen in
natural or artificial light; for example, clouds, fog, rain, sleet, hail, or snow.
20. ”Passenger Convenience Items” means those items related to passenger convenience, comfort or
entertainment such as, but not limited to, galley equipment, movie equipment, ash trays, stereo equipment,
overhead reading lamps, etc.
