AD 95-17-05 Airworthiness Directives; Airbus Model A310 Series Airplanes

Models named: A310 series. Read the applicability below — it usually turns on serial or part numbers too.

All Model A310 series airplanes, certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must use the authority provided in paragraph (d) of this AD to request approval from the FAA. This approval may address either no action, if the current configuration eliminates the unsafe condition; or different actions necessary to address the unsafe condition described in this AD. Such a request should include an assessment of the effect of the changed configuration on the unsafe condition [[Page 43519]] addressed by this AD. In no case does the presence of any modification, alteration, or repair remove any airplane from the applicability of this AD.

Required as indicated, unless accomplished previously. To prevent an undampened free fall of the left- and right-hand main landing gear (MLG), which subsequently could lead to the inability to retract the MLG and damage to other airplane systems, accomplish the following: (a) Within 60 days after the effective date of this AD, perform an inspection to detect loose self-locking nuts and damaged (sheared or marked) cotter pins on the actuating cylinder to drag strut attachment of the left- and right-hand MLG, in accordance with Messier Bugatti Airbus A310 Service Bulletin 470-32-744, dated March 31, 1993, or Revision 1, dated January 13, 1994; or Airbus Service Bulletin A310-32-2069, Revision 1, dated December 13, 1994. Repeat this inspection thereafter at intervals not to exceed 500 landings. (1) If no nut is loose or no cotter pin is damaged, prior to further flight, install a new cotter pin, in accordance with the service bulletin. After replacement, continue to repeat the inspection at intervals not to exceed 500 landings (2) If any nut is loose or any cotter pin is damaged (sheared or marked), prior to further flight, replace the nut, washer, and cotter pin with a new nut, washer, and cotter pin; and torque tighten the nut; in accordance with the service bulletin. After replacement, continue to repeat the inspection at intervals not to exceed 500 landings. (b) Within 5 days after accomplishing the requirements of paragraph (a) this AD, report all inspection results, positive or negative, to Messier-Bugatti and Airbus Industrie in accordance with Messier-Bugatti Airbus A310 Service Bulletin 470-32-744, dated March 31, 1993, or Revision 1, dated January 13, 1994.

(c) Modification of the actuating cylinder/drag strut attachment of the MLG, in accordance with Messier Bugatti Airbus A310 Service Bulletin 470-32-760, dated December 31, 1993, as revised by Change Notice 1, dated January 28, 1994; or Airbus Service Bulletin A310- 32-2076, Revision 1, dated December 13, 1994; constitutes terminating action for the repetitive inspection requirements of this AD. (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113.
