To preclude failure of the main landing gear truck pivot pins, P/N 1523058-101 or -103, perform the following, unless already accomplished:

(a) Within the next 50 hours time in service after the effective date of this AD, unless already accomplished, or unless paragraph (b) or (c), below, has already been accomplished, perform a visual inspection of the open end inside surface of the truck pivot pins in accordance with Lockheed wire PSC/78-46863-OL, dated October 25, 1978. If there is a visual indication of a crack, the pin must be inspected before further flight in accordance with paragraph (b) of this AD, or replaced with a new pin.

NOTE: For most reliable results, the above visual inspection should be conducted with a good source of light and a mirror, and only after the open end inside surface is thoroughly cleaned of all accumulated dirt and grease.

(b) Within the next 300 hours time in service after the effective date of this AD, unless already accomplished or unless paragraph (c) has already been accomplished, perform the ultrasonic inspection of the open end inside surfaces in accordance with Part I of Lockheed- California Company Service Bulletin 093-32-149, Revision 2.

(1) If there is no ultrasonic indication or if it is not in excess of Standard (Reflector) "A", repeat the inspection at 300 hours time in service intervals until paragraph (c) is accomplished.

(2) If there is an ultrasonic indication in excess of Standard (Reflector) "A", but less than one inch in the Standard (Reflector) "B" location repeat the inspection at 150 hours time in service intervals until paragraph (c) is accomplished.

(3) If there is an ultrasonic indication in excess of one inch in the Standard (Reflector) "B" location remove the cracked pin and replace with like serviceable item before next flight.

(c) Install landing gear truck pivot pin "fail-safe" retainer per Part 2 of Lockheed- California Company Service Bulletin 093-32-149, Revision 2 in accordance with the following schedule:

(1) Within 1500 hours time in service from the effective date of this AD for all aircraft except as provided otherwise in paragraph (c)(2).

(2) Within 2500 hours time in service from the effective date of this AD for aircraft which have been satisfactorily inspected per the requirement of Part 2 of Lockheed- California Company Service Bulletin 093-32-135.

NOTE: The installation of the above "fail-safe" retainer is considered to be an interim safety action.

(d) Within twelve (12) calendar months after the effective date of this AD, accomplish the installation or modification of the main landing gear uplock snubber, truck pivot pin and bushings using Kits 1630462-101, -103, -105, and -107, or alternate Kits 1630462-109, -111, - 113, and -115, in accordance with Lockheed-California L-1011 Service Bulletin 093-32-154, Revision 2, dated January 5, 1981, or later revisions approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region. Compliance with this paragraph constitutes terminating action for this AD.

(e) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections required by this AD.

(f) Equivalent inspection procedures and truck pin retainer installation may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.
