Rear Bulkhead Cracks
During a routine inspection, maintenance personnel found cracked and deformed structure in the aft fuselage area including horizontal stabilizer forward spar attachment structure, spar support angles, and stiffeners. The AYA working with the FAA and True Flight Aerospace was instrumental in the issuance of Special Airworthiness Information Bulletin (SAIB) CE-09-37 After the original issuance of this SAIB on July 1, 2009, a second airplane was found to have damage in this area which prompted True Flight Aerospace (the Type Certificate holder) to issue Critical Service Bulletin SB-192, dated August 20, 2009 and the revision of the SAIB to CE-09-37R1 which includes reference to SB-192.
Both SB-192 and the SAIB contain one major error: Only the AA5 is listed when both really should apply to the entire AA5 and AG5 series.
The fact that there had been no reported accidents due to the cracking aided in the FAA decision not to issue an Airworthiness Directive (AD) but to make it an SAIB. SB-192 can be found on the GOPA Website Member Menu under Maintenance Files. It contains detailed inspection and repair information.
This is another example of how you’re Type Club, the GOPA (formerly AYA) works for you – researching aircraft problems and working with the TC holder and the FAA to provide critical maintenance information to you and your mechanic.
