Airworthiness Directives; Raytheon Aircraft Company 90, 100, 200, and 300 Series Airplanes

Riepilogo

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) 90, 100, 200, and 300 series airplanes (formerly known as Beech Aircraft Corporation 90, 100, 200, and 300 series airplanes). This AD requires: checking the airplane maintenance records from January 1, 1994, up to and including the effective date of this AD, for any MIL-H-6000B fuel hose replacements on the affected airplanes; inspecting any replaced rubber fuel hose for a spiral or diagonal external wrap with a red stripe the length of the hose with 94519 printed along the stripe; and replacing any MIL-H-6000B rubber fuel hose matching this description with an FAA-approved hose having a criss-cross or braided external wrap. This AD was prompted by a report of a product defect by the manufacturer that could cause fuel system blockage and engine stoppage. The actions specified by this AD are intended to prevent fuel flow interruption, which could lead to uncommanded loss of engine power and loss of control of the airplane.
