Unsafe condition
This AD was prompted by a report of cracks and geometrical non-conformities of the TRBs; all cracks initiated in the drain hole area at the blade root section. The FAA is issuing this AD to address geometrical non-conformities of the TRBs, which could lead to crack initiation and consequent blade failure, and possible loss of control of the helicopter.
Affected ADs
None.
