Airworthiness Directive · Amendment 39-17716 · Windows
Airbus Airplanes
This AD applies to Airbus Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-111, -211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes; certificated in any category; all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports of certain sliding windows that were difficult to operate after landing. This AD requires a detailed inspection to identify part numbers of sliding windows and sliding window seals, and modification if necessary. This AD also includes an optional replacement. We are issuing this AD to detect and correct incorrect seals, which could lead to the functional loss of the sliding window as an exit, possibly preventing the flightcrew from safely evacuating the airplane during an emergency.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 750 flight cycles or 750 flight hours or 4 months after the effective date of this AD, whichever occurs first: Do a detailed inspection to identify part numbers (P/Ns) of each window and seal of the left-hand (LH) and right-hand (RH) sliding windows and sliding window seals, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-56-1016, including Appendices 01 and 02, dated September 14, 2012. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the window and seal of the LH and RH sliding windows and sliding window seals can be conclusively determined from that review.
If a sliding window part number identified in table 1 to paragraph (h) of this AD is found during the inspection required by paragraph (g) of this AD; and the serial number of the part does not have the modification amendment letter “M,” and does have sliding window seals having P/N 22-17-7640-1 or P/N 22-17-7640-2 installed: Within the compliance time specified in paragraph (g) of this AD, modify the sliding window seal (which includes adding the letter “M” to serial number of the affected part), in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-56-1015, dated September 14, 2012.

For sliding windows identified as affected in paragraph (h) of this AD, replacement of a sliding window seal having P/N 22-17-7640-1 L/H or P/N 22-17-7640-2 R/H with a seal having P/N 22-17-7640-3 L/H or P/N 22-17-7640-4 R/H, respectively, in accordance with a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, or the European Aviation Safety Agency (EASA) (or its delegated agent), is an acceptable alternative method of compliance with the modification required by paragraph (h) of this AD.
Note 1 to paragraph (i) of this AD: Guidance for replacement of a sliding window seal can be found in Page Block 401 of Sub-section 56-12-11 of the Airbus A318/A319/A320/A321 Aircraft Maintenance Manual.
(1) Airplanes on which Airbus Modification 153512 (installation of sliding window with P/N NP165312-13 and P/N NP165312-14 with improved seal) or Modification 153534 (installation of sliding window with P/N NP165312-11 and P/N NP165312-12 with amendment M) has been embodied in production are not affected by the requirements of paragraphs (g) and (h) of this AD, provided that no sliding window or sliding window seal has been replaced since first flight.
(2) Airplanes on which Airbus Modification 39587 (installation of affected seal on PPG Aerospace sliding windows) has not been embodied in production are not affected by the requirements of paragraphs (g) and (h) of this AD, provided that no sliding window or sliding window seal has been replaced since first flight.
As of the effective date of this AD, no person may install on any airplane any PPG Aerospace sliding window with a part number listed in table 1 to paragraph (h) of this AD with a seal having P/N 22-17-7640-1 or P/N 22-17-7640-2, unless the seal has been modified in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-56-1015, dated September 14, 2012; or PPG Aerospace Service Bulletin 165312-56-001, dated February 29, 2012.
