## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all General Electric Company (GE) GEnx-1B64, 1B64/P1, -1B64/P2, - 1B67, -1B67/P1, -1B67P2, -1B70, -1B70/75/P1, -1B70/75/P2, -1B70/P1, - 1B70/P2, -1B70C/P1, -1B70C/P2, -1B74/75/P1, -1B74/75/P2, -1B76/P2, and -1B76A/P2 model turbofan engines. This proposed AD was prompted by reports of combustor case burn-through. This proposed AD would require installation of electronic engine control (EEC) software, version B205 or later. The FAA is proposing this AD to address the unsafe condition on these products.
