Airworthiness Directive · Amendment 39-15409 · Tail rotor drive--tail rotor drive shaft
Eurocopter France Model EC130 B4 Helicopters
This AD applies to Model EC130 B4 helicopters, with a tail rotor drive center section shaft, part number (P/N) 350A340202; and bearing, P/N 593404, certificated in any category.
We are adopting a new airworthiness directive (AD) for Eurocopter France Model EC130 B4 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The European Safety Agency (EASA), the Technical Agent for France, with which we have a bilateral agreement, states in the MCAI:
Within 50 hours time-in-service (TIS) or 3 months, whichever occurs first, unless already done, do the following actions.
(1) Inspect for cracks or loosened rivets in the tube-to-flange attachment of the tail rotor drive center section shaft and inspect the perpendicularity of bearing No. 1 in compliance with the Accomplishment Instructions, paragraph 2.B.2., of Eurocopter Alert Service Bulletin No. 65A002, dated November 16, 2005 (ASB).
(2) If a crack or loosened rivet is found, replace the tail rotor drive center section shaft before further flight.
(3) If the out-of perpendicularity of the bearing is more than 0.1 mm, apply the corrective procedure described in the Accomplishment Instructions, paragraph 2.B.2., of the ASB.
None.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Safety Management Group, Rotorcraft Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Ed Cuevas, Aviation Safety Engineer, Fort Worth, Texas 76193-0111, telephone (817) 222-5355, fax (817) 222-5961.
(2) Airworthy Product: Use only FAA-approved corrective actions. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent) if the State of Design has an appropriate bilateral agreement with the United States. You are required to assure the product is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
