## The airworthiness directive

77-15-14 MORANE SAULNIER (SOCATA): Amendment 39-2985. Applies to Model MS 760 (Paris 1) and MS 760A (Paris 1A) airplanes, all serial numbers, certificated in all categories, that are equipped with ERAM wheels, P/N 3760-A.

Compliance is required within the next 50 hours time in service after the effective date of this AD, unless already accomplished within the preceding 50 hours time in service, and thereafter, at intervals not to exceed 100 hours time in service from the last inspection.

To detect cracks in the landing gear wheels and prevent possible wheel failure, accomplish the following:

  (a) Visually inspect, using a dye penetrant procedure, each ERAM wheel, P/N 3760-A, in accordance with paragraph 2 of ERAM Service Bulletin No. 32-01, dated December 1970, as revised October 1973, or an FAA-approved equivalent.

  (b) If, during an inspection required by this AD, a wheel is found to have more than one crack per stud or any crack exceeding 14 mm in length, replacethat wheel with a serviceable wheel of the same part number or an FAA-approved equivalent.

This amendment becomes effective August 29, 1977.
