Airworthiness Directive 2007-11-20
one-timeAirworthiness Directives; General Electric Company (GE) CF6-80 Series Turbofan Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for GE CF6-80 series turbofan engines with fuel shroud retaining rings, part number (P/N) J204P0084, installed. This AD requires replacing those retaining rings with a more robust design fuel shroud retaining snap ring. This AD results from two events of external engine fuel leakage and a subsequent under-cowl engine fire. We are issuing this AD to prevent an under-cowl engine fire and damage to the airplane during an engine high vibration event.
Which aircraft AD 2007-11-20 applies to
Applies to CF6-80C2 models that have incorporated GE SB CF6-80C2 S/B 73-0253 (or were built with the drainless manifold configuration in production) and to CF6-80E1 models that have incorporated GE SB CF6-80E1 S/B 73-0026 (or were built drainless), in each case with one or more fuel shroud retaining rings P/N J204P0084 installed. Installed on, but not limited to, Airbus A300, A310, A330, Boeing 747, 767, and McDonnell Douglas MD11 airplanes.
Whether AD 2007-11-20 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.
