## Summary

We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B64/P2, -1B67/P2, -1B70/P2, -1B70/75/P2, -1B70C/P2, and -1B74/75/P2 turbofan engines. This proposed AD was prompted by a report of the failure of the high-pressure turbine (HPT) stage 1 blade retainer and subsequent in-flight shutdown of the engine. This proposed AD would require inspection of the HPT stage 1 blade retainer. We are proposing this AD to address the unsafe condition on these products.
