### ATA 35 Oxygen – Chemical E mergency O xygen C ontainer s – Modification

Manufacturer(s): Airbus (formerly A irbus I ndustrie ) 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 aeroplane s , all manufacturer serial numbers ( MSN )

. Reason: It has been determined that oxygen gen erators, installed on a specific batch of Type 1 ( 22 min) passenger emergency oxygen container assemblies, may be come detached by extreme pulling of the mask tube at the end of oxygen supply. Investigations revealed that such detachment can be caused by th e increas e in temperature to wards the end of the generator operation, which may weaken the plastic housing in the attachment area of the bracket.. Th is condition , if not corrected, could make the rivets slip through the plastic housing , causing a ‘hot’ ox ygen generator and mask to fall down, possibly resulting in injury to passenger s . For the reasons described above, t his AD require s modification of the affected oxygen container assembl ies

. This AD also prohibits the installation of the affected (unmodifie d) containers on any aeroplane as replacement parts. Effective Date: 1 7 April 2012EASA PAD No. 20 1 2 - 0 0 5 5 EASA PAD No :11 - XXX
