General Electric Company CF6-80C2 Series Turbofan Engines
General Electric Company (GE) CF6-80C2 series turbofan engines, with Accessory Gearbox (AGB) idler adapters, Part Number (P/N) 9395M78G08 that had been reworked from a P/N 9395M78G06 configuration using GE CF6-80C2 Service Bulletin (SB) 72-743, dated August 25, 1994, excluding those parts that were repaired by GE Repair Document 032-273-S1, dated April 8, 1998. These engines are installed on but not limited to Airbus A300 and A310 series, and Boeing 747, 767, and MD-11 aircraft.
This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company CF6-80C2 series turbofan engines. This action requires a one-time visual inspection to ensure the correct accessory gearbox (AGB) idler adapter inserts are installed, and, if necessary, removal of AGB idler adapters with the improper inserts. This amendment is prompted by a report of a failure of a fuel tube flange connection due to improper AGB idler adapter inserts that resulted in a high pressure fuel leak and engine fire. The actions specified in this AD are intended to identify and remove AGB idler adapters with improper inserts, which can result in an engine fire and damage to the aircraft.
