## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6-80 series turbofan engines having fuel shroud retaining snap rings, part number (P/N) J204P0084, installed. This proposed AD would require replacing those snap rings with a more robust design snap ring. This proposed AD results from two events of external engine fuel leakage and a subsequent under-cowl engine fire. We are proposing this AD to prevent an under-cowl engine fire and damage to the airplane during a high engine vibration event.
