## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Brantly Helicopters Industries U.S.A. Co., Ltd., Model 305 helicopters and Brantly International, Inc., Model B-2, B-2A, and B-2B helicopters. This proposed AD was prompted by a report of a crack in the tail rotor (T/R) hub. This proposed AD would require repetitive inspections of the T/R hub and depending on the results, removing the T/R hub from service. The FAA is proposing this AD to address the unsafe condition on these products.
