### TITLE: OXYGEN - PASSENGER OXYGEN - INTRODUCE IMPROVED TYPE I (22MIN) CHEMICAL OXYGEN CONTAINER FOR SVA02 VERSION **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR None MINOR 152453K15242 NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Tests have shown that the oxygen generators, installed on an identified batch of 22 minute oxygen container assemblies, may come detached by extreme pulling of the mask tube at the end of oxygen supply. This detachment is caused by the increasing temperature to the end of the generator operation, which may weaken the plastic housing in the attachment area of the bracket. Possibly the rivets can slip through the plastic housing and the generator and the masks can fall down. It is necessary to install an improved reinforcement plate. This Service Bulletin has been issued to inform the operators about the issue of the B/E Aerospace Systems Service Bulletin 1XC22-0100-35-006, which details the installation of the reinforcement plate. The accomplishment of this Service Bulletin will ensure the correct attachment of the oxygen generators.

E. COMPLIANCE (1) Classification RECOMMENDED: Service Bulletin recommended to be accomplished to prevent significant operational disruptions. (2) Accomplishment Timescale Table 1, Config. 001 - Introduce improved type 1 oxygen containers Condition Action Compliance time Whichever occurs first All Aircraft Modify the type 1 oxygen containers 6000 Flight Hours (FH) or 4500 Flight Cycles (FC) or 20 months from original AIRBUS Service Bulletin issue date This Service Bulletin has been classified Recommended. It is expected that an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued to change this classification to Mandatory. It is anticipated that the AD will confirm the thresholds given above but reference should be made to the AD for confirmation of the mandated accomplishment timescale. F. APPROVAL The technical content of this document is approved under the authority of Design Organisation Approval No. EASA.21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin. G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances. The estimates do not include the time to prepare, plan or inspect the work. Manufacture and procurement of parts and tools, drying times for paints, sealants, etc., and general administration work are also not included.
