### Design Approval Holder’s Name: AIRBUS Type/Model designation(s): A318, A319, A320 and A321 aeroplanes TCDS Number: EASA.A.064 F oreign AD: Not applicable Supersedure : None



### ATA 56 Windows – Cockpit Sliding W indow S eals – Inspection / Modification Manufacturer(s): Airbus ( formerly Airbus Industrie) Applicability: Airbus A318 - 111, A318 - 112, A318 - 121, A318 - 122, A319 - 111, A319 - 112, A319 - 113, A319 - 114, A319 - 115, A319 - 131, A319 - 132, A319 - 133, A320 - 111, A320 - 211, A320 - 212, A320 - 214, A320 - 215, A320 - 216, A320 - 231, A320 - 232, A320 - 233, A321 - 111, A321 - 112, A321 - 131, A321 - 211, A321 - 212, A321 - 213, A321 - 231 and A321 - 232 aeroplanes, all manufacturer serial numbers

. Reason: Several occurrences have been reported on A320 family aeroplanes of PPG sliding window s that were difficult to operate after landing. The i nvestigation results revealed that when a seal having Part Number ( P/N ) 22 - 17 - 7640 - 1 or P/N 22 - 17 - 7640 - 2 is installed on a sliding window , closure of the window can create a vacuum between the 2 tubes of the pressure seal, leading to the window remaining stuck to the frame on the fuselage side, due to suction effect. This condition, if not detected and corrected, could lead to the functional loss of the sliding window as an exit, possibly preventing the flight crew from safely evacuating the aeroplane duri ng an emergency . For the reasons described above, this AD requires a one - time detailed i nspection (DI) of the sliding windows and its seal to identify the affected sliding window seals and , depending on findings, accomplishment of the applicable corrective actions.

Required A ction(s) and Compliance Time(s) : Required as indicated, unless accomplished previously: (1) Within 750 f light c ycle s or 750 f light hours or 4 months , whichever occurs first after the effect ive date of this AD, accomplish a DI of the l eft - hand (LH) and r ight - hand (RH) sliding windows and sliding window seals in order to identify the P/N of each window and seal in accordance with the instructions of Airbus Service Bulletin (SB) A320 - 56 - 1016. A review of aeroplane maintenance records is acceptable to make this determination, in lieu of the instructions of Airbus SB A320 - 56 - 1016, if the P/N and manufacturing dates of the installed sliding windows and sliding window seals can be conclusively identified from that review. (2) If , during the DI as required by paragraph (1) of this AD, a sliding window P/N is identified as listed in Table 1 of this AD without modification amendment M, and sliding window seal s P/N 22 - 17 - 7640 - 1 or P/N 22 - 17 - 7640 - 2 are installed, before next flight, modify the sliding window seal in accordance with the instructions of Airbus SB A320 - 56 - 1015
