Airworthiness Directive · Amendment 39-9266 · BAE Systems (Operations) Limited Airplanes
BAE Systems (Operations) Limited Airplanes
This AD applies to BAE Systems (Operations) Limited Jetstream Model 4101.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Jetstream Model 4101 airplanes, that requires replacement of a certain pressure switch with a certain new pressure switch in the fuel system for the engines. This amendment is prompted by a report indicating that the current design of a certain pressure switch in the fuel system for the engines does not meet current fire resistant properties, which could result in the failure of the pressure switch during a fire in the engine compartment. The actions specified by this AD are intended to prevent failure of the existing pressure switch in the fuel system for the engines, which, during an engine fire, could result in fuel leakage that could add fuel to the fire.
