Abstract
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 and -300 series airplanes. This action requires replacement of the switch guard on the switch used to control the passenger and/or therapeutic oxygen system with a new, improved switch guard. This action is necessary to prevent displacement of the passenger/therapeutic oxygen switch, which could result in the unavailability of supplemental/therapeutic oxygen and possible incapacitation of passengers during flight. This action is intended to address the identified unsafe condition.
