89-22-11 AIRBUS INDUSTRIE: Amendment 39-6364. Docket No. 89-NM-115-AD.

Applicability: Model A300 B4-103 and B4-203 series airplanes, equipped with main landing gear (MLG) barrel hinge arms, Messier Part Number C65381-4 or -6, certificated in any category.

Compliance: Required within 12 months after the effective date of this AD, unless previously accomplished.

To prevent collapse of one main landing gear, accomplish the following:

A. Except as provided in paragraph B., below, replace all main landing gear (MLG) hinge arms having a pad cadmium coating, with either hinge arms that do not have a pad cadmium coating or hinge arms that have been reconditioned in accordance with MHB Service Bulletin 470- 32-652, dated December 30, 1988. Replacement is required in accordance with the procedures specified in Airbus Industrie Service Bulletin A300-32-390, Revision 1, dated December 20, 1988.

NOTE: Airbus Service Bulletin A300-32-390 references Messier-Hispano-Bugatti (MHB) Service Bulletin 470-32-651 for additional replacement procedures.

B. The following airplanes are not subject to the requirements of this AD:

1. Airplanes equipped with MLG hinge arms to which a pad cadmium coating has been applied in accordance with Airbus Industrie Service Bulletin A300-26-356, dated May 15, 1985 (which references MHB Service Bulletin 470-32-422), and have since undergone a main workshop overhaul and have been subjected to an electrolytic cadmium stripping and replating in a bath.

2. Airplanes equipped with MLG hinge arms that have been reconditioned in accordance with MHB Service Bulletin 470-32-652.

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, Standardization Branch, ANM-113, FAA, Northwest Mountain 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, Standardization Branch, ANM-113.

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 Airbus Industrie, Airbus Support Division, Avenue Didier Daurat, 31700 Blagnac, France. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or the Standardization Branch, 9010 East Marginal Way South, Seattle, Washington.
