To prevent failure of certain main landing gear components, within 180 days after the effective date of this AD or prior to accumulation of the number of landings specified in each paragraph below, whichever occurs later, accomplish the following, unless previously accomplished:
A. Prior to the accumulation of 13,000 landings, replace the shock absorber sliding rod attachment fittings, part numbers C61643-4 and C61643-5, with reinforced components in accordance with the instructions of Messier-Hispano-Bugatti (MHB) Service Bulletin 470-32-172, Revision 1, dated June 10, 1981, for aircraft having the serial numbers specified in Airbus Industrie (AI) Service Bulletin A300-32-148, Revision 1, dated December 29, 1978.
B. Prior to the accumulation of 5,000 landings, inspect the trunnion on the actuating cylinder side of the hinge arm, part number C65381-2, in accordance with the instructions of MHB Service Bulletin 470-32-386, Revision 1, dated September 30, 1981, on airplanes having serial numbers specified in AI Service Bulletin A300-32-328, dated August 31, 1981.
1. If no corrosion is found, install a seal to improve the lubrication of the hinge arm trunnion in accordance with the instructions of MHB Service Bulletin 470-32-385, dated August 14, 1981 (related to AI Service Bulletin A300-32-326, dated August 31, 1981), and repeat the above inspections at intervals not to exceed 2,000 landings.
2. If corrosion or cracks are found, remove the corrosion and cracks in accordance with the instructions of MHB Service Bulletin 470-32-386, Revision 1, dated September 30, 1981, and install the seal in accordance with paragraph B.1, above. Repeat the above inspections at intervals not to exceed 250 landings.
3. If the depth of material removed when performing the reworkof subparagraph B.2 is greater than one millimeter from the original profile, replace the hinge arm prior to further flight.
C. Prior to the accumulation of 6,500 landings and thereafter at intervals not to exceed 400 landings, inspect the lateral inboard trunnion of the hinge arms, part numbers C65381- 2 and C65381-4, for cracks in accordance with the instructions of MHB Service Bulletin 470-32- 442, dated March 31, 1983, for aircraft having serial numbers specified in AI Service Bulletin A300-32-365, dated June 27, 1983.
1. For hinge arms that have incorporated modification MHB 595 in the trunnion located in the inboard position on the actuating cylinder side, the time limit is to be counted from the date of reconditioning. For all other cases, the time limit is to be counted from the day the arm was put into service.
2. The repetitive inspections required in paragraph C, above, may be terminated when the actions described in paragraph 2.C of MHB Service Bulletin 470-32-442, on the inboard, outboard, and forward trunnions are accomplished.
D. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.
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 and/or modifications required by this AD.
