Airworthiness Directive; General Electric Company CF6-45/50 Series Turbofan Engines

The General Electric Company (GE) is proposing a new airworthiness directive (AD) for its CF6-45/50 series turbofan engines, requiring inspections for cracks in the high pressure compressor disk lock slots and removal from service after 6,000 cycles. The proposal aims to prevent stage 14 high pressure compressor disk failure, which could lead to engine failure and aircraft damage.
