Applicability: Model 382 series airplanes, serial numbers 3946 through 4637, certificated in any category. Compliance: Required as indicated, unless previously accomplished. To prevent failure of the nose landing gear strut assembly, accomplish the following: A. Within the next 250 hours time-in-service after the effective date of this AD, and thereafter at intervals not to exceed 3,150 hours time-in-service, perform an inspection for corrosion of the nose landing gear strut assembly, part number 388071-3, in accordance with Lockheed Service Bulletin 382-32-31, dated September 5, 1979. 1. If corrosion is detected which is within the limits specified in the service bulletin, rework in accordance with the service bulletin prior to further flight. 2. If corrosion is detected which is outside the limits specified in the service bulletin, prior to further flight, accomplish one of the following: a. Replace the defective cylinder assembly, part number 371675-1 with a serviceable cylinder assembly; or b. Modify the nose landing gear strut and components in accordance with Lockheed Service Bulletin 382-32-23, dated March 17, 1978. B. Modification of the nose landing gear strut and components in accordance with Lockheed Service Bulletin 382-32-23, dated March 17, 1978, constitutes terminating action for the inspection requirements of this AD. C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Atlanta Aircraft Certification Office, FAA, Central Region. NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, Atlanta Aircraft Certification Office. D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD. All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Lockheed Aeronautical Systems Company, 86 South Cobb Drive, Marietta, Georgia 30063.
