AD: Sikorsky Aircraft Corporation (Sikorsky) Helicopters

AD NUMBER: 2015-04-05

PRODUCT: Certain Sikorsky Model S-76A, B, C, and D helicopters.

ACTION: Final Rule; request for comments

SUMMARY: This AD requires inspecting the tail rotor drive shaft (TDS) flange-to-shaft attachment hardware for correct assembly and correct torque of the fasteners.

If there is a discrepancy, this AD requires, before further flight, applying an index mark to the flange and TDS, inspecting the flange and shaft for a crack, fracture, wear, and certain measurements, and replacing any part that does not meet the approved criteria before further flight.

This AD is prompted by a partial loss of tail rotor drive resulting in a forced landing.

The actions specified by this AD are intended to prevent failure at the flange-to-shaft attachment, loss of a tail rotor drive, and subsequent loss of control of the helicopter.

DATES: This AD becomes effective March 12, 2015. Comments must be recieved by April 27, 2015.

FMI: AD
