low-pressure flex-hose if necessary. This AD reLlts from reports of a low-pressure

flex-hase afthe flightcrew axygen system that +med through due ta inadvertent

electrical current from a short circuit in an adjacent audio select panel. We are issuing

tilis AD ta prevent inadvertent electrical currentl which can cause the law-pressure
