Airworthiness Directive · Amendment 39-12750 · General Electric Company CF6-80E1A2 Turbofan Engines
General Electric Company CF6-80E1A2 Turbofan Engines
This airworthiness directive (AD) is applicable to General Electric Company CF6-80E1A2 turbofan engines. These engines are installed on, but not limited to, Airbus Industrie A330 series airplanes.
This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company (GE) CF6-80E1A2 turbofan engines. This action requires replacing a certain low pressure turbine rotor (LPTR) shaft at or before reaching a new reduced life cycle limit. This amendment is prompted by an updated low cycle fatigue (LCF) analysis of the LPTR shaft. The actions specified in this AD are intended to prevent LCF cracking and failure of the LPTR shaft due to exceeding the life limit, which could result in an uncontained engine failure and damage to the airplane.
