Airworthiness Directives; Raytheon Corporate Jets Model BAe 125- 1000A and Hawker 1000 Series Airplanes

Краткое содержание

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Raytheon Corporate Jets Model BAe 125-1000A and Hawker 1000 series airplanes. This action requires an inspection to detect damage and to determine the clearance between the hydraulic pipes, adjacent pipes/components, and electrical looms/cables; and repair or replacement, if necessary. This amendment is prompted by reports of chafing of an electrical loom/cable on a hydraulic pipe and of chafing between a hydraulic pipe and an adjacent pipe. The actions specified in this AD are intended to prevent loss of hydraulic pressure, electrical malfunction, or an in-flight fire due to abrasion of electrical loom/cable insulation, eventual electrical shorting of the cable, and subsequent burning of a pinhole in a pipe.
