AD NUMBER: 97-01-13
SUBJECT HEADING: Airworthiness Directives; Cessna 100, 200, 300, and 400 Series Airplanes
ACTION: Final rule; request for comments
SUMMARY: This amendment adopts a new airworthiness directive (AD) that applies to Cessna Aircraft
Company (Cessna) 100, 200, 300, and 400 series airplanes. This action requires checking the airplane
maintenance records for any fuel, oil, or hydraulic hose, Cessna part number (P/N) S51-10, replaced between
March 1995 and February 3, 1997 (the effective date of this AD); immediately checking any of these hoses
for a diagonal or spiral external reinforcement wrap; and immediately replacing any of these hoses that have
a diagonal or spiral external reinforcement wrap with one that has a crisscross external reinforcement wrap.
This action was prompted by reports of operators experiencing a loss of engine power because of low fuel
feed, in addition to Cessna discovering that the rubber hose installed at the factory on certain Cessna Models
208 and 208B airplanes was defective. The Cessna P/N S51-10 rubber hose is utilized on fuel, oil, and
hydraulic hoses on the affected airplanes. The actions specified by this AD are intended to prevent fuel, oil,
or hydraulic systems failure caused by a collapsed hose.
DATES: Effective February 3, 1997.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA has recently received several incident reports of fuel flow blockage to the engines of certain Cessna
208 series airplanes. Examination of the Cessna part number (P/N) S51-10 rubber hoses installed on these
airplanes revealed a deterioration to the point of delamination of the inner tube from the external wrap. This
rubber hose is utilized on fuel, oil, and hydraulic hoses on Cessna 100, 200, 300, and 400 series airplanes.
This kind of deterioration eventually causes the rubber hose to collapse, which could result in failure of the
fuel, oil, or hydraulic systems.
Further investigation revealed this particular rubber hose was manufactured by Buckeye Rubber Products
Company in January 1995, and Cessna purchased 300 feet of this hose for factory installation on certain
Cessna Models 208 and 208B airplanes between March 1995 and June 1995. The remaining portion of hose
about:blank 1/7
30/11/24, 11:49 about:blank
was distributed in March 1995 as replacement hose. With this in mind, the Cessna P/N S51-10 hose could be
installed by field approval on any Cessna 100, 200, 300, and 400 series airplanes, as well as at manufacture
on certain Cessna Models 208 and 208B airplanes.
Relative Service Information
Cessna has issued the service bulletins presented below, which include ACCOMPLISHMENT
INSTRUCTIONS for (1) checking for the installation of fuel, oil, and hydraulic hoses, Cessna P/N S51-10,
with a diagonal or spiral external reinforcement wrap, and (2) replacing any of these hoses that have a

The FAA's Determination
After examining the circumstances and reviewing all available information related to the incidents described
above, including the referenced service information, the FAA has determined that AD action should be taken
to prevent fuel, oil, or hydraulic systems failure caused by a collapsed hose.
Explanation of the Provisions of This AD
Since an unsafe condition has been identified that is likely to exist or develop in other Cessna 100, 200, 300,
and 400 series airplanes of the same type design, the FAA is issuing an AD. This AD requires checking the
airplane maintenance records for any fuel, oil, or hydraulic hose, Cessna part number (P/N) S51-10, replaced
between March 1995 and February 3, 1997 (the effective date of this AD); immediately checking any of these
hoses for a diagonal or spiral external reinforcement wrap; and immediately replacing any of these hoses that
have a diagonal or spiral external reinforcement wrap with one that has a crisscross external reinforcement
wrap. Accomplishment of the hose check and replacement is required in accordance with the service bulletins
referenced previously.
Determination of the Effective Date of the AD
Since a situation exists that requires the immediate adoption of this regulation, it is found that notice and
opportunity for public prior comment hereon are impracticable, and that good cause exists for making this
amendment effective in less than 30 days.
Compliance Time of This AD
about:blank 2/7
30/11/24, 11:49 about:blank
The compliance time of this AD is presented in calendar time and hours time-in-service (TIS). Delamination
of the rubber hose inner tubing and separation of the inner tube from the external wrap is caused by an error
in manufacturing. This condition can develop regardless of whether the airplane is in flight. The breakdown
of the hose may not be noticed initially, but as the hose continues to erode, collapse is inevitable, which could
result in fuel, oil, or hydraulic systems failure. For these reasons, the FAA is requiring a compliance time of
specific hours TIS and calendar time (the prevalent one being that which occurs first).
Comments Invited
Although this action is in the form of a final rule that involves requirements affecting immediate flight safety
and, thus, was not preceded by notice and opportunity to comment, comments are invited on this rule.
Interested persons are invited to comment on this rule by submitting such written data, views, or arguments
as they may desire. Communications should identify the Rules Docket number and be submitted in triplicate
to the address specified above. All communications received on or before the closing date for comments will
be considered, and this rule may be amended in light of the comments received. Factual information that
supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD
action and determining whether additional rulemaking action would be needed.
Comments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of
the rule that might suggest a need to modify the rule. All comments submitted will be available, both before
and after the closing date for comments, in the Rules Docket for examination by interested persons. A report
that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules
Docket.
Commenters wishing the FAA to acknowledge receipt of their comments submitted in response to this notice
must submit a self-addressed, stamped postcard on which the following statement is made: "Comments to
Docket No. 96-CE-46-AD." The postcard will be date stamped and returned to the commenter.
Regulatory Impact
The regulations adopted herein will not have substantial direct effects on the States, on the relationship
between the national government and the States, or on the distribution of power and responsibilities among
the various levels of government. Therefore, in accordance with Executive Order 12612, it is determined that
this final rule does not have sufficient federalism implications to warrant the preparation of a Federalism
Assessment.
The FAA has determined that this regulation is an emergency regulation that must be issued immediately to
correct an unsafe condition in aircraft, and is not a significant regulatory action under Executive Order
12866. It has been determined further that this action involves an emergency regulation under DOT
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency
regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory
evaluation will be prepared and placed in the Rules Docket (otherwise, an evaluation is not required). A copy
of it, if filed, may be obtained from the Rules Docket.
