## Summary

The Federal Aviation Administration (FAA) proposes to adopt a new airworthiness directive (AD) that is applicable to General Electric Company CF6-50 and CF6-80C2 turbofan engines. This proposal would require replacement of certain existing CF6-50 and CF6-80C2 shrouds with new design shrouds. This proposal is prompted by 37 low pressure turbine (LPT) uncontained events on the CF6-50 and 24 on the CF6-80C2 engine models since 1993, and the development and certification of newly designed shrouds that will improve LPT containment capability. The actions specified by the proposed AD are intended to prevent uncontained engine failure and possible airplane damage.
