Airworthiness Directive · Amendment 39-9733 · Textron Aviation Inc. Airplanes
Textron Aviation Inc. Airplanes
This AD applies to Textron Aviation Inc. BAe.125 Series 1000A, BAe.125 Series 800A, Hawker 1000, Hawker 800.
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 Beech (Raytheon) Model BAe 125-800A and -1000A, and Model Hawker 800 and 1000 series airplanes, that requires modification of the TKS metering pump in the airframe ice protection system. This amendment is prompted by a report that the pump was found fitted with silver plated wiring. The actions specified by this AD are intended to ensure that silver plated wiring is removed from these pumps; silver plated wiring carrying a direct current can ignite the ice protection fluid (glycol) when exposed to it, which could result in a possible fire hazard.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
