This amendment adopts a new airworthiness directive (AD), applicable to General Electric Company (GE) CF6-80C2 series turbofan engines, that requires a repetitive oil quantity check after engine start-up but prior to taxi, and installation of a flame arrestor plug support (FAPS) in the aft end of the center vent tube as a terminating action to the repetitive oil quantity checks. This amendment is prompted by three reports of uncontained engine failure due to separation of the fan mid shaft. The actions specified by this AD are intended to prevent an uncontained engine failure and inflight engine shutdown due to fuel contamination of the oil system.
