MODIFICATION CLASSIFICATION

MAJOR None

MINOR 152449K15238

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.

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.
