2008-25-06 Airbus: Amendment 39-15764. Docket No. FAA-2008-1274; Directorate Identifier 2008-NM-197-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December 26, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Airbus Model A319-131, A319-132, A319-133, A320-231, A320-232, A320-233, A321-131, A321-231, and A321-232 series airplanes, certificated in any category; all serial numbers equipped with International Aero Engine (IAE) Model V2500-A1 engines or Model V25xx-A5 series engines. (The "xx'' is used in the series engine reference to indicate various numbers listed in the type certificate data sheet.)
Subject
(d) Air Transport Association (ATA) of America Code 71: Powerplant.
Reason
(e) The mandatory continued airworthiness information (MCAI) states:
DGAC-France AD 90-079-009(B) R1 [and corresponding FAA AD 90-22- 08, amendment 39-6781 (corrected on November 8, 1990, 55 FR 47028)] introduced an inspection and daily rectification action on Airbus A320-231 aircraft in order to prevent failure of one or more of the engine rear mount barrel nuts.
Subsequent to the above problem, Airbus has advised that an incorrect part number has been introduced in the IPC (illustrated parts catalog) (reference 71-22-11 Figure 80B item 180) for the rear engine mount barrel nut. This problem affects Airbus A319, A320 and A321 models with IAE V2500-A5 engines.
The part number introduced in error is not certificated for the IAE V2500-A5 engine installation and, if installed, may fail in service.
This Airworthiness Directive (AD) * * * mandates the inspections required to determine the standard of barrel nut installed and the corrective actions, as necessary, for the aircraft with V2500-A1 or -A5 engines installed.
Failure of the rear engine mount barrel nut could result in reduced structural integrity of the rear engine mount and possible separation of the engine from the airplane, and a consequent hazard to the airplane and persons and property on the ground. Required actions include inspecting for broken barrel nuts. The corrective actions include replacing the barrel nut with a different barrel nut and replacing the associated bolts, washers, and retainers; and contacting Airbus for corrective action if any affected barrel nut is found broken and doing that corrective action.
Actions and Compliance
(f) Unless already done, do the following actions for airplanes equipped with IAE model V2500-A1 engines: Within 7 days after the effective date of this AD, conduct a records review to determine if barrel nut part number (P/N) 83644-1612 is installed, in accordance with paragraph 5.1 of Airbus All Operator Telex (AOT) A320-71A1045, dated October 17, 2008.

(2) For airplanes on which itcannot be positively determined from a records review that P/N 83644-1612 is not installed: Within 7 days after the effective date of this AD, do the visual inspections of the barrel nut for part numbers and for broken nuts in accordance with paragraph 5.2 of Airbus AOT A320-71A1045, dated October 17, 2008.
(i) If one or more barrel nuts are found broken, before further flight contact Airbus for corrective actions and do the corrective actions.

(1) For airplanes for which it can be positively determined from a records review that P/N 83644-1612 is not installed, no further action is required by this paragraph.
(2) For airplanes on which it cannot be positively determined that P/N 83644-1612 is not installed: Within 7 days after the effective date of this AD, do the visual inspections of the barrel nut for part numbers and for broken nuts, in accordance with paragraph 4.2 of Airbus AOT A320-71A1045, dated October 17, 2008.
