Airworthiness Directives; Raytheon (Beech) Model 400A and 400T Series Airplanes
Abstract
This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon (Beech) Model 400A and 400T series airplanes, that requires a one-time inspection to detect incorrect wiring of the engine fire extinguisher bottle squibs, and corrective action, if necessary. It also requires a modification to the wiring and the addition of wire harness and bottle labeling for future reference. This amendment is prompted by reports of incorrect wiring of the engine fire extinguisher bottle squibs. The actions specified by this AD are intended to prevent failure of the engine fire extinguisher bottle to discharge, or discharge of the wrong engine fire extinguisher bottle.
Applicability
Aircraft makes and models this AD applies to, sorted by US-registered fleet size.
Compliance instructions
The full AD text — required actions, compliance times, parts/serial numbers, and methods of compliance — is in the Federal Register publication. We do not paraphrase ADs because misreading the compliance instructions is a safety risk.
