Airworthiness Directive · Amendment 39-10253 · Raytheon Model Hawker 1000 Series Airplanes
Raytheon Model Hawker 1000 Series Airplanes
Model Hawker 1000 series airplanes; serial numbers 258151, 258159, and 259003 through 259052 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon Model Hawker 1000 series airplanes, that requires modifying the aft core cowl nozzles of the engine nacelles. This amendment is prompted by a report indicating that the sealant on the core cowl nozzles may extend higher than the forward flange of the core cowl nozzles, which could result in contact between the cowl sealant surface and the lever of the engine mechanical over-speed control system. The actions specified by this AD are intended to prevent such contact, which could cause the over-speed system to function improperly and consequent engine structural failure.
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.
