AD: AgustaWestland S.p.A. Helicopters

AD NUMBER: 2014-07-51

PRODUCT: Certain AgustaWestland S.p.A. Model AB139 and AW139 helicopters.
ACTION: Final rule; request for comments.

SUMMARY: This AD requires repetitively inspecting the Main Rotor (M/R) Rotating Scissors for play of the Lower Half Scissor Spherical Bearing (bearing) and removing the bearing if there is play beyond allowable limits.

This AD also requires removing all affected bearings. This AD is prompted by reports of certain bearings dislodging from certain M/R Rotating Scissors.

These actions are intended to detect excessive play of the bearing and prevent failure of the M/R Rotating Scissors and subsequent loss of control of the helicopter.

DATES: This AD becomes effective August 20, 2014 to all persons except those persons to whom it was made immediately effective by Emergency AD (EAD) No. 2014-07-51, issued on March 27, 2014, which contains the requirements of this AD. Comments must be received by October 6, 2014.
