Airworthiness Directive · Amendment 39-12595 · General Electric Company CF6-80E1 Model Turbofan Engines
General Electric Company CF6-80E1 Model Turbofan Engines
Superseded. A later AD replaced this one: AD 2004-09-34. Comply with the one in force.
This airworthiness directive (AD) is applicable to General Electric Company CF6-80E1 engine models with high pressure turbine (HPT) stage 2 (S2) nozzle guide vane (NGV) part numbers (P/N's) 1647M84G09 or 1647M84G10. These engines are installed on, but not limited to, Airbus A330 airplanes.
This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company CF6-80E1 model turbofan engines. This action requires flex borescope inspections of high pressure turbine (HPT) stage two (S2) nozzle guide vanes (NGV) installed in CF6-80E1 model turbofan engines. This amendment is prompted by an uncontained engine failure attributed to HPT S2 NGV distress. The actions specified in this AD are intended to prevent blade failure from HPT S2 NGV distress, which could result in an uncontained engine failure.
