Revised 1/24/02 Airworthiness Concern Sheet
Donald O. Young Aircraft Safety Engineer Small Airplane Directorate Atlanta Aircraft Certification Office, ACE-118A One Crown Center, 1895 Phoenix Blvd, Ste 450 Atlanta, GA 30349 770-703-6079 don.o.young@faa.gov Make, Model, Series, Serial No.: Cessna Model 182Q & 182R, S/N’s 18266128, 18266578, 18266698, 18267112, 18267338, 18267469, 18267484, 18267619, 18267642, 18268393, 18268405, 18280791, 18281164 Reason for Airworthiness Concern: An unsafe condition has been found to exist in Cessna Model 182Q & 182R airplanes modified by EASA STC No. EASA.A.S.00774 and is likely to exist or develop in aircraft modified by FAA STC No. SA03302AT.
Date: September 12, 2008 FAA Description of Airworthiness Concern (Who, What, Where, When, How? Attachments: RA and appropriate data) On January 21, 2008, SMA France reported that two Cessna Model 182 airplanes modified by EASA STC to incorporate SMA SR 305-230 aircraft diesel engines experienced forced landings in France due to significant engine power loss. EASA issued AD 2008-0078 and accepted SMA Service Bulletin SB-C182-75-002, Revision 2, as nonterminating compliance. That SB requires inspection and on-condition replacement of hoses, improved clamping, and subsequent repetitive inspections. We are concerned that airplanes modified by similar FAA STC may have the same condition. SMA has since issued SB-C182-75-004, which requires installation of reworked intercoolers and new hoses and specifies improved hose engagement; compliance is a condition of warrantee and is offered at no cost to owners.
SMA is revising ICA’s to include improved installation and inspection instructions included in this Service Bulletin.
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 FAA requests comments from the AOPA and EAA regarding service experience and results of periodic inspections of intercooler hose installations on airplanes incorporating STC SA03302AT. Information provided by owners/operators may be considered in any airworthiness action if warranted.

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.
