## 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, -1B67/P2, -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 a report of a crack in the outer fuel manifold causing fuel leakage. This proposed AD would require initial and repetitive visual inspections of the cushioned loop clamp (''p-clamp'') and, depending on the results of the inspection, a spot fluorescent penetrant inspection (FPI) of the outer fuel manifold. Depending on the results of the FPI, this proposed AD would require replacement of the outer fuel manifold. This proposed AD would also require initial and repetitive replacements of the p- clamp. The FAA is proposing this AD to address the unsafe condition on these products.
