Models named: A300 series, A310 series, A300-600 series. Read the applicability below — it usually turns on serial or part numbers too.

Model A300 series airplanes listed in Airbus Service Bulletin A300-53-0300, dated October 28, 1993; Model A310 series airplanes listed in Airbus Service Bulletin A310-53-2077, dated October 28, 1993; and Model A300-600 series airplanes listed in Airbus Service Bulletin A300-53-6055, dated October 28, 1993; on which Airbus Modification No. 10414 or production equivalent has not been installed; certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise 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 request approval for an alternative method of compliance in accordance with paragraph (g) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Required as indicated, unless accomplished previously. To prevent failure of the electric rack-to-structure attachment points, which could subsequently result in loss of airplane systems, structural damage, and possible electrical arcing, accomplish the following: (a) Prior to the accumulation of 7,000 total flight cycles, or within 50 flight cycles after the effective date of this AD, whichever occurs later, perform a detailed visual inspection of the right-and left-hand lower attachments of electric rack 101VU, including the crossbeams at frames 15A and 16, to detect missing fasteners, cracked fitting angles, or elongated fastener holes, in accordance with Airbus Service Bulletin A300-53-0300 (for Model A300 series airplanes), dated October 28, 1993; Airbus Service Bulletin A310-53-2077 (for Model A310 series airplanes), dated October 28, 1993; or Airbus Service Bulletin A300-53-6055 (for Model A300-600 series airplanes), dated October 28, 1993; as applicable. Note 2: Inspections accomplished in accordance with Airbus Industrie All Operator Telex (AOT) 53-03, Revision 3, dated December 23, 1992, prior to the effective date of this AD, are considered acceptable for compliance with the inspection requirements of this paragraph. (b) If no discrepancies are identified during the inspection required by paragraph (a) of this AD, repeat the detailed visual inspection thereafter at intervals not to exceed 2,300 flight cycles. (c) If any fastener is missing or is found to be damaged during any inspection required by this AD, prior to further flight, replace the fastener in accordance with Airbus Service Bulletin A300-53-0300 (for Model A300 series airplanes), dated October 28, 1993; Airbus Service Bulletin A310-53-2077 (for Model A310 series airplanes), dated October 28, 1993; or Airbus Service Bulletin A300-53-6055 (for Model A300-600 series airplanes), dated October 28, 1993; as applicable. (d) If any fitting angle is found to be cracked during any inspection required by this AD, prior to further flight, install Modification No. 10414 in accordance with Airbus Service Bulletin A300-53-0294 (for Model A300 series airplanes), dated May 17, 1993; Airbus Service Bulletin A310-53-2076 (for Model A310 series airplanes), dated May 17, 1993; or Airbus Service Bulletin A300-53- 6046 (for Model A300-600 series airplanes), dated May 17, 1993; as applicable. Installation of this modification constitutes terminating action for the inspections required by this AD. (e) If any crossbeam is found damaged during any inspection required by this AD, prior to further flight, repair it in accordance with a method approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. (f) Installation of Modification No. 10414 in accordance with Airbus Service Bulletin A300-53-0294 (for Model A300 series airplanes), dated May 17, 1993; Airbus Service Bulletin A310-53-2076 (for Model A310 series airplanes), dated May 17, 1993; or Airbus Service Bulletin A300-53-6046 (for Model A300-600 series airplanes), dated May 17, 1993; as applicable; constitutes terminating action for the inspections required by this AD. (g) 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. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (h) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. (i) The inspections and replacement shall be done in accordance with Airbus Service Bulletin A300-53-0300, dated October 28, 1993; Airbus Service Bulletin A310-53-2077, dated October 28, 1993; or Airbus Service Bulletin A300-53-6055, dated October 28, 1993; as applicable.
