AD NUMBER: 2014-22-51

PRODUCT: Airbus Helicopters (formerly Eurocopter France) Model EC130T2 helicopters, which was sent previously to all known U.S. owners and operators of these helicopters.

ACTION: Final Rule; Request for comments

SUMMARY: This AD requires repetitively inspecting the attachment points where the fan attaches to the main gearbox (MGB) oil cooler hopper (hopper) and replacing any cracked hopper with an airworthy hopper.

This AD is prompted by several cases of a cracked hopper. The cracks were found on the hopper at the fan attachment points.

These actions are intended to detect a crack in the hopper at a fan attachment point to prevent failure of the fan attachment, interference of the fan with the control rod of the front servo-control or with the flight control bellcrank, and subsequent loss of control of the helicopter.

DATES: This AD becomes effective February 25, 2015 to all persons except those persons to whom it was made immediately effective by Emergency AD (EAD) 2014-22-51, issued on October 29, 2014, which contained the requirements of this AD. Comments must be received by April 13, 2015.
