83-13-05 AIRBUS INDUSTRIE: Amendment 39-4675. Applies to the model A300 series airplanes, certificated in all categories. To prevent failure of certain components of the main and nose landing gears, within 250 landings after the effective date of this AD or prior to the accumulation of the number of landings specified in each paragraph below, whichever occurs later, accomplish the following, unless previously accomplished:
A. Reinforce the lower torque link pins of the main landing gear in accordance with the instructions of Messier-Hispano-Bugatti (MHB) Service Bulletin 470-32-065, dated September 3, 1976, prior to the accumulation of 12,000 landings on B1 model aircraft, and 16,000 landings on B2-100, B2-200, B2-300, B4-100, B4-200 and C4-200 model aircraft, having the serial numbers specified in Airbus Industrie (AI) Service Bulletin A300-32-077, Revision 1, dated February 19, 1980.
B. Modify the main landing gear drag strut of aircraft with serial numbers specifiedby AI Service Bulletin A300-32-114, dated January 13, 1978, in accordance with the instructions of MHB Service Bulletin 470-32-110, dated November 28, 1977, prior to the accumulation of 20,000 landings.
C. Modify the actuating cylinder of the main landing gear for aircraft with serial numbers specified by AI Service Bulletin A310-32-116, Revision 6, dated September 17, 1982, in accordance with the instructions of MHB Service Bulletin 470-32-108, Revision 1, dated November 24, 1978, according to the following schedule:
1. For aircraft with modifications AI 1799 and 2025 originally installed, prior to the accumulation of 32,000 landings on B2 models or 22,000 landings on B4 models.
2. For aircraft with modifications AI 1799 and 2025 not originally installed, prior to the accumulation of 12,000 landings on both models B2 and B4.
D. Incorporate modifications MHB 151 and 161 on the shock strut connecting rod of the main landing gear of aircraft with serial numbers specified in AI Service Bulletins A300-32- 096, Revision 4, and A300-32-076, Revision 3, both dated September 17, 1982, in accordance with the instructions of MHB Service Bulletins 470-32-039 and 470-32-040, Revision 1, both dated October 31, 1980, prior to the accumulation of 12,000 landings.
E. Incorporate modification MHB 59 on the brace assembly actuating cylinder of the main landing gear of aircraft with serial numbers specified in AI Service Bulletin A300-32-036, Revision 2, dated September 17, 1982, in accordance with the instructions of MHB Service Bulletin 470-32-031, dated January 8, 1976, prior to the accumulation of 17,500 landings.
F. Replace the actuating cylinder piston of the nose landing gear of aircraft with serial numbers specified in AI Service Bulletin A300-32-904, Revision 5, dated September 17, 1982, in accordance with the instructions of MHB Service Bulletin 470-32-033, dated January 9, 1976, prior to the accumulation of 14,000 landings.
G. For the purpose of this AD, and when approved by an FAA maintenance inspector, the number of landings may be computed by dividing each airplane's time in service by the operator's fleet average time from takeoff to landing for the aircraft type.
H. 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.
I. 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.
This amendment becomes effective July 7, 1983.
