The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319-100, A320-200, A321-100, and A321-200 series airplanes. This AD requires repetitive inspections for corrosion in the inside and outside lower walls of each type A, D, E, and F lavatory wall that has at least one wall-mounted cabin attendant seat, and related investigative and corrective actions if necessary. The repetitive inspections may be terminated by repairing the wall with composite material, or replacing the entire wall with a new wall made of composite material. This AD results from reports of corrosion in the lower part of the lavatory walls due to water ingress. We are issuing this AD to detect and correct corrosion and damage on the lower part of the lavatory walls, which could compromise the structural integrity of the cabin attendant seat attachments, and cause injury to the cabin attendants during a crash landing.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For the purposes of this AD, unless otherwise specified, the term “service bulletin” means the Accomplishment Instructions of Airbus Service Bulletin A320-25-1365, dated February 18, 2005.
Within 2,400 flight hours or 15 months after the effective date of this AD, whichever occurs earlier: Do a detailed inspection for corrosion and damage in the inside and outside lower walls of each type A, D, E, and F lavatory wall that has at least one wall-mounted CAS, and do all applicable related investigative and corrective actions as applicable, including any supporting non-destructive testing and related investigative actions. Do all actions in accordance with the procedures and time-frames defined in the Accomplishment Instructions of the service bulletin. Repeat the inspection at the applicable time specified in Figure 1 Sheet 1 of the service bulletin.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
Doing the permanent repair in paragraph (h)(1) or (h)(2) of this AD terminates the repetitive inspection requirements of this AD.
(1) Repair the aluminum wall with composite material in accordance with a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Direction Générale de l'Aviation Civile (or its delegated agent). The applicable lavatory component maintenance manual (CMM) in paragraph (h)(1)(i), (h)(1)(ii), (h)(1)(iii), or (h)(1)(iv) of this AD is one approved method.
(i) Airbus CMM Lavatory A 25-41-51.
(ii) Airbus CMM Lavatory D 25-43-51.
(iii) Airbus CMM Lavatory E 25-41-52.
(iv) Airbus CMM Lavatory F 25-43-53.
(2) Replace the aluminum wall with a new wall made of composite material in accordance with the Accomplishment Instructions of the applicable service bulletin in paragraph (h)(2)(i), (h)(2)(ii), or (h)(2)(iii) of this AD.
(i) For lavatory A: Airbus Service Bulletin A320-25-1289, Revision 01, dated October 29, 2003.
(ii) For lavatories D and E: Airbus Service Bulletin A320-25-1365, dated February 18, 2005, which references Airbus CMM Lavatory D 25-43-51; and Airbus CMM Lavatory E 25-41-52, as applicable, as an additional source of service information for doing the replacement.
(iii) For lavatory F: Airbus Service Bulletin A320-25-1357, dated July 19, 2004.
(i) Replacement of the lavatory A wall done before the effective date of this AD in accordance with Airbus Service Bulletin A320-25-1289, dated October 11, 2002, is acceptable for compliance with the requirements of paragraph (h)(2)(i) of this AD.
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.
