### TITLE: MULTIPROG - CREW OXYGEN - INSPECTION OF OXYGEN PIPE FOR CORROSION **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Some production oxygen pipe assemblies located within the crew oxygen distribution system have been found to be affected by internal corrosion. The potentially corroded oxygen pipe assembly is installed at the end of the Right Hand (RH) crew distribution line just upstream of the First Officer and RH Observer oxygen mask boxes. This condition could lead to no or insufficient oxygen supply to one flight crew member since corrosion particles may obstruct the crew oxygen mask filter and could under some conditions lead to an increase of the fire risk. As the affected batches of oxygen pipes have been identified, this Inspection Service Bulletin details the work required to check all the potentially impacted aircraft for corrosion and to replace the pipe if necessary. Accomplishment of this Inspection Service Bulletin permits: - determining if the pipe is part of the affected batches of potentially corroded pipes, - replacing it if necessary.
