Airworthiness Directives; Raytheon Aircraft Company 90, 99, 100, 200, and 300 Series Airplanes

概要

The FAA proposes to supersede Airworthiness Directive (AD) 98- 15-13, which applies to certain Raytheon Aircraft Company 90, 100, 200, and 300 series airplanes. This proposed supersedure adds the Raytheon Beech 99 series to the applicability listed in AD 98-15-13. No change in the compliance action is proposed for those aircraft originally affected by AD 98-15-13. AD 98-15-13 currently requires you to check the airplane maintenance records from January 1, 1994, up to and including the effective date of that 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 or orange- red stripe along 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. We are issuing this proposed AD to prevent fuel flow interruption, which could lead to uncommanded loss of engine power and loss of control of the airplane.
