Airworthiness Directives; General Electric Company Turbofan Engines

We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) CF6-80C2 and CF6-80E1 turbofan engines. This proposed AD was prompted by reports of a burn-through of the accessory heat shield during an accessory compartment fire leading to an engine fire. This proposed AD would require replacing the accessory heat shield assembly. We are proposing this AD to prevent high- temperature gas ingestion into the accessory compartment, engine fire, and damage to the airplane.
