The FAA proposes to supersede Airworthiness Directive (AD) 2018-15-04, which applies to 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- 80C2B2, CF6-80C2B2F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2D1F, CF6-80C2L1F, and CF6-80C2K1F model turbofan engines. AD 2018-15-04 requires ultrasonic inspection (UI) of high-pressure turbine (HPT) stage 1 and stage 2 disks. Since we issued AD 2018-15-04, GE determined the need to expand the population of affected disks. This proposed AD would retain the required inspections while expanding the population of affected disks. The FAA is proposing this AD to address the unsafe condition on these products.
