Airworthiness Directive 95-07-03
one-timeAirworthiness Directives; AlliedSignal Aerospace GTCP85 Series Auxiliary Power Units
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to AlliedSignal Aerospace (formerly Garrett Auxiliary Power Division and Garrett Turbine Engine Co.) GTCP85 series auxiliary power units (APU), that requires modifying the APU to install an exhaust centerbody. This amendment is prompted by reports of two uncontained APU failures where turbine wheel fragments exited the APU exhaust axially and damaged the aircraft. The actions specified by this AD are intended to prevent an axially uncontained APU failure and damage to the aircraft.
Which aircraft AD 95-07-03 applies to
Applies to GTCP85 series auxiliary power units (APUs) with model numbers listed in AlliedSignal SB No. GTCP85-49-6919 Rev 1 (dated Jan 15, 1995), except those installed on Boeing 737 and BAe BAC 1-11 series aircraft; and per ASB No. GTCP85-49-A6831 Rev 1 (dated Jan 15, 1995), APUs having a one-piece cast turbine rotor with the listed part numbers. Installed on but not limited to Boeing 707/727, Lockheed L382, and McDonnell Douglas DC-8-70/DC-9/MD-80 series aircraft.
Whether AD 95-07-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
