## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-1A, CF34-3A, CF34-3A1, CF34-3A2, CF34-3B, and CF34-3B1 model turbofan engines. This proposed AD was prompted by an in-flight failure of a fan blade that led to an in-flight shutdown. This proposed AD would require removal and replacement of the affected fan blades. The FAA is proposing this AD to address the unsafe condition on these products.
