Trenton D. Shepherd Propulsion Aerospace Engineer ACE-116W Propulsion 1801 Airport Road, Room 100 Wichita, KS 67203 316-946-4135 trent.shepherd@faa.gov Make, Model, Series, Serial No.:
Cessna Model 182H, 182J, 182K, 182L, 182M, 182N, 182P, 182Q and 182R Reason for Airworthiness Concern:
Fire in the engine compartment.
Date: 7 March 07 FAA Description of Airworthiness Concern (Who, What, Where, When, How? Attachments: RA and appropriate data) The installation of STC SA00152WI places the electrical cable between the ground power receptacle and starter relay in close proximity to fuel lines and the fuel strainer control cable. This routing has resulted in interference between the electrical cable, primary fuel line, and/or fuel strainer cable. Chafing of these components has resulted in one documented engine fire, emergency landing, and significant damage to the airplane. Currently there are 215 aircraft in the field with this STC installed.
There has been one documented incident of engine compartment fire relating to this STC installation.
Request for Information (Proposed Alternate Inspection/Repair Procedures, Cost Impact, Etc. Note: Any comments or replies to the FAA need to be as specific as possible. Please provide specific examples to illustrate your comments/concerns.):
The STC holder is considering rerouting the existing electrical cable via issuance of a mandatory service bulletin. The FAA is considering an immediately adopted AD.

At this time, the FAA has not made a determination on what type of corrective action (if any) should be taken. The resolution of this airworthiness concern could involve an AD action or an SAIB, or the FAA could determine that no action is needed at this time. The FAA’s final determination will depend in part on the information received in response to this ACS.
The FAA endorses dissemination of this technical information to all manufacturers and requests association and type clubs comments.
