## The airworthiness directive

85-07-07 SOCIETE NATIONALE INDUSTRIELLE AEROSPATIALE (SNIAS): Amendment 39-5020. Applies to Model SE3130, SE313B, SA3180, SA318B, SA318C, and SA315B helicopters, certificated in all categories, that are equipped with a tail rotor pitch change control rod that has been modified in accordance with AMS2178.

Compliance is required within 50 hours time in service after the effective date of the AD or before the accumulation of 750 hours total time in service for tail rotor gearboxes, whichever occurs later, unless already accomplished.

To ensure that proper shot peening of the control rod has been accomplished and thereby prevent possible cracks in the control rod, accomplish the following:

  (a) Comply with paragraph C of Aerospatiale Service Bulletin No. 01.19 or No. 01.50, dated May 2, 1984, for the appropriate helicopter model. Paragraph C of each bulletin contains disassembly, inspection, and assembly information.

  (b) Equivalent means of complying with this AD must be approved by the Manager, Aircraft Certification Office, FAA, Europe, Africa, and Middle East Office, c/o American Embassy, Brussels, Belgium.

  (c) Aircraft may be flown in accordance with FAR Sections 21.197 and 21.199 to a base where compliance may be accomplished.

  (d) The Director of the Federal Register approved the incorporation by reference of the manufacturer's specifications and procedures identified and described in this directive pursuant to 5 U.S.C. 552(a)(1). Persons may obtain copies of the service bulletins upon request to Aerospatiale Helicopter Corporation, 2701 Forum Drive, Grand Prairie, Texas 75051, Attention: Customer Support. The documents may be examined at the Office of the Regional Counsel, Southwest Region, Federal Aviation Administration, 4400 Blue Mound Road, Fort Worth, Texas.

This amendment becomes effective April 19, 1985.
