AD NUMBER: 2007-11-20
MANUFACTURER: General Electric
SUBJECT: Airworthiness Directive 2007-11-20 SUMMARY: 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.
