## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that currently requires an inspection to detect damage of the wire bundles in the left side of the flight compartment in the vicinity of the stowage box for the captain's oxygen mask, and repair, if necessary; a continuity check on repaired wires; installation of sleeving over the wire bundles; and rerouting of the wire bundles. This amendment requires modifications of the captain's and first officer's consoles in the flight compartment to ensure adequate clearance between oxygen equipment and adjacent wire bundles. This amendment is prompted by reports indicating that chafed wiring and wire insulation wear occurred in the vicinity of the stowage box for the captain's oxygen mask due to interference between oxygen line fittings and adjacent wire bundles. The actions specified by this AD are intended to prevent such chafing and inadequate clearance, which could result in electrical arcing and consequent oxygen leakage in the vicinity of the stowage box; these conditions, if not corrected, could result in a fire in the flight compartment.
