Airworthiness Directives; Gulfstream Model G-V Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Gulfstream Model G-V series airplanes. This action requires a one-time inspection to measure the clearance between a certain wiring harness and the crew oxygen bottle; corrective actions, if necessary; and eventual relocation of the crew oxygen bottle and rework of the lines and tubing associated with the crew and passenger oxygen bottles. This amendment is prompted by a report indicating that interference between the wiring harness and the crew oxygen bottle was found on a production airplane. The actions specified in this AD are intended to prevent chafing of the wiring harness against the crew oxygen bottle, which could result in electrical shorting and possible fire in the underfloor structure of the airplane.
