Airbus Airplanes
This AD applies to the Airbus airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Model A318-111, -112, -121, and -122 airplanes.
(2) Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes.
(3) Model 320-211, -212, -214, -231, -232, and -233 airplanes.
We are superseding Airworthiness Directive (AD) 2012-18-12 for certain Airbus Model A318, A319, and A320 series airplanes. AD 2012-18- 12 required modifying the off-wing escape slide (OWS) enclosures on the left-hand (LH) side and right-hand (RH) side of the fuselage. This new AD retains the requirements of AD 2012-18-12 and expands the applicability to all Airbus Model A318, A319, and A320 series airplanes. This AD was prompted by reports that additional OWS part numbers have been affected. We are issuing this AD to prevent off-wing exits on the LH and RH sides of the fuselage from becoming inoperative. During an emergency, inoperative off-wing exits could impair the safe evacuation of occupants, possibly resulting in personal injuries.
This paragraph restates the requirements of paragraph (g) of AD 2012-18-12, with no changes. For airplanes equipped with OWS enclosures having part number (P/N) D31865-109, D31865-110, D31865-209, or D31865-210, except as provided by paragraph (i)(1) of this AD: Within 36 months after October 22, 2012 (the effective date of AD 2012-18-12), modify the OWS enclosures and install an OWS enclosure having P/N D31865-309, D31865-311, D31865-310, or D31865-312 on the LH side and RH side of the fuselage, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-25-1649, dated February 16, 2010.
For airplanes equipped with an OWS enclosure having P/N D31865-101, D31865-102, D31865-103, D31865-104, D31865-105, D31865-106, D31865-107, or D31865-108, except as provided by paragraph (i)(2) of this AD: Within 36 months after the effective date of this AD, modify the OWS enclosures and their aspirators in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-25-1156, Revision 03, dated December 5, 2001.
(1) Airplanes having Airbus Modification 30088 embodied in production using an OWS enclosure having P/N D31865-111 or D31865-112 are not affected by the requirements of paragraph (g) of this AD, unless a replacement OWS enclosure, having a part number listed in paragraphs (k)(9) through (k)(12) of this AD, has been installed on that airplane since first flight.
(2) Airplanes on which Airbus Modifications 24850, 25844, and 27275 have been embodied in production, or on which modifications of the LH and RH OWS enclosures and their aspirators have been accomplished using Airbus Service Bulletin A320-25-1156, Revision 01, dated February 2, 1999; or Revision 02, dated October 26, 1999; and Airbus Service Bulletin A320-25-1265, dated June 6, 2001, are compliant with the modification requirement of paragraph (h) of this AD.
Installing both LH and RH OWS that have been modified in accordance with the Accomplishment Instructions of Air Cruisers Service Bulletin A320 004-25-84, Revision 4, dated November 9, 2012, is an acceptable method of compliance with the modification required by paragraph (g) of this AD.
As of the effective date of this AD, do not install on any airplane an OWS enclosure having a part number listed in paragraphs (k)(1) through (k)(12) of this AD.
(1) D31865-101.
(2) D31865-102.
