Airworthiness Directives; General Electric Company Turbofan Engines


We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6-80A, CF6-80A1, CF6-80A2, CF6- 80A3, CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, CF6- 80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6-80C2B1F1, CF6-80C2B1F2, CF6- 80C2B2, CF6-80C2B2F, CF6-80C2B3F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2B8F, CF6- 80C2D1F, CF6-80C2L1F, and CF6-80C2K1F turbofan engines. This proposed AD was prompted by an uncontained failure of a high-pressure turbine (HPT) stage 2 disk. This proposed AD would require ultrasonic inspection (UI) of HPT stage 1 and 2 disks. We are proposing this AD to address the unsafe condition on these products.
