Applies to Model A300 series airplanes, certificated in all categories, with main landing gear hinge arms, P/N C65-381-2, which have accumulated more than 2,500 takeoff/landing cycles and which have not been modified in accordance with Airbus Industrie Service Bulletin No. A300-32-118, dated August 21, 1979.
Compliance required as indicated, unless already accomplished.
To prevent failure of the main landing gear hinge arms, accomplish the following:
(a) Within the next 8 hours time in service after the effective date of this AD, and thereafter at intervals not to exceed 12 hours time in service from the last inspection, but at least once each operating day, visually inspect the main landing gear hinge arms, P/N C65-381-2, for cracks in accordance with Airbus Industrie All Operators Telex AOT 32/80/105/SC1/0644/EM/AK/ME, dated March 21, 1980, and AOT 32/80/107/SC1/0795/EM/AK/ME, dated April 8, 1980, or FAA approved equivalents.

(b) the hinge arm between the fork webs and cylindrical lugs or MLG actuator attachments.
(c) the surrounding area of the cylindrical attachment lugs.
(b) If the inspection required by paragraph (a) of this AD reveals cracks in a hinge arm, prior to further flight, replace the affected hinge arm with a serviceable hinge arm, P/N C65- 381-2 or P/N C65-381-4, in accordance with Airbus Industrie Service Bulletin No. A300-32-118. Repetitive inspections may be discontinued upon installation of P/N C65-381-4 hinge arms.

(d) Cracked hinge arms must be replaced prior to further flight.
(e) Accomplishment of paragraph (c) of this AD terminates the visual inspection requirements of paragraph (a).
(f) Airplanes may be ferried in accordance with FAR Sections 21.197 and 21.199 to a place where the inspections and or repairs can be made in order to comply with this AD.
(g) Upon request of an operator and submission of substantiating data, the Chief, Aircraft Certification Staff, AEU-100, Europe, Africa, and Middle East Office, c/o American Embassy, Brussels, Belgium,may upon recommendation of the cognizant FAA aviation safety inspector, adjust the inspection intervals.
(h) If an equivalent means of compliance is used in complying with this AD, that equivalent must be approved by the Chief, Aircraft Certification Staff, AEU-100, Europe, Africa, and Middle East Office, c/o American Embassy, Brussels, Belgium.
All persons affected by this directive who have not already received the referenced documents from the manufacturer may obtain copies upon request to Airbus Industrie, Airbus Support Division, B.P. 33, 31700 Blagnac, France.
