Airbus Airplanes
This AD applies to Airbus Model A320-214, -232, and -233 airplanes; and Airbus Model A321-211 and -231 airplanes, certificated in any category, having manufacturer serial numbers (MSNs) 5583, 5598, 5602, 5604, 5608, 5610, 5613 through 5622 inclusive, 5624 through 5627 inclusive, 5629 through 5632 inclusive, 5634 through 5636 inclusive, 5638, 5640 through 5644 inclusive, 5646 through 5649 inclusive, 5651 through 5653 inclusive, 5655, 5657 through 5661 inclusive, 5663, 5665, 5667, 5670, 5672, 5673, and 5675.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A320-214, -232, and -233 airplanes; and Airbus Model A321- 211 and -231 airplanes. This AD was prompted by reports of incorrect installation of jiffy joint connectors on cables connected to certain passenger service units (PSUs), which could cause the passenger oxygen container to malfunction if the connector becomes disengaged during flight due to vibration. This AD requires identification of the affected PSUs, and depending on findings, doing applicable related investigative and corrective actions. We are issuing this AD to prevent failure of the door of the passenger oxygen container to open in the event of airplane decompression, resulting in lack of oxygen supply and consequent injury to occupants.
Within 7,500 flight hours or 26 months after the effective date of this AD, whichever occurs first, do an inspection to identify the part number and serial number of each PSU, and if an affected part number or serial number is found, do all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-25-1B20, dated October 9, 2014. Do all applicable related investigative and corrective actions within 7,500 flight hours or 26 months after the effective date of this AD, whichever occurs first. An affected PSU part number or serial number is one listed in Attachment 1, “List of affected PSU PNR and S/N,” of Airbus Operations GmbH Vendor Service Bulletin Z315H-25-004, dated September 26, 2014. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number and serial number of the PSU can be conclusively determined from that review.
On page 13 of Airbus Operations GmbH Vendor Service Bulletin Z315H-25-004, dated September 26, 2014, Table 4 (“List of Attachments”) under the heading “APPENDIX” identifies “Attachment 1, `List of affected PSU PNR and S/N.' ” The attachment is not numbered or dated.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
