This AD results from a drawing review and further associated inspections that highlighted a potential chafing risk between the third crew member's oxygen mask box and feeder cables routed in the area. We are issuing this AD to prevent chafing between the subject oxygen mask box and the adjacent feeder cables, which could generate smoke or fire in the cockpit that could be fanned by oxygen leakage from the oxygen mask box.
