## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for various restricted category helicopters, originally manufactured by Sikorsky Aircraft Corporation (Sikorsky), Model EH-60A, HH-60L, S-70, S-70A, S-70C, S-70C(M), S-70C(M1), and UH-60A. This proposed AD would require initial and recurring inspections of the main rotor (M/R) blade spindle cuff for a crack. This proposed AD is prompted by multiple reports of a cracked M/R blade spindle cuff. The proposed actions are intended to prevent an unsafe condition on these products.
