The Boeing Company Revises Airworthiness Directive for Certain Airplanes to Prevent Ignition Source and Inlet Valve Jam

The Boeing Company is revising an earlier proposed airworthiness directive for certain 737, 747, 767, and 777 models to require operators to inspect and label crew oxygen mask stowage box units that have already been inspected and reworked, and to allow the installation of new or serviceable units to prevent ignition sources and inlet valve jams.
