Analysis
Shortly after departure, the turbine engine lost total power. The pilot attempted to land on the remaining runway, but overran the departure end and collided with terrain. The left wing sustained substantial damage. The turbine engine and associated governor were removed from the airplane and examined. No anomalies were detected with the engine or components which would have contributed to the loss of engine power. The reason for the loss of engine power could not be determined.
Factual narrative
On October 8, 2019, about 1445 central daylight time, a Beech A36 airplane, N396JG, was substantially damaged when it was involved in an accident near Waukesha, Wisconsin. The pilot and passenger were uninjured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to information obtained by Federal Aviation Administration inspectors, the airplane departed the Waukesha County Airport (KUES), Waukesha, Wisconsin, using runway 18. About 200 ft above ground level, while still over the departure end of the runway, the engine lost total power. The pilot attempted to land on the remaining runway but overran the departure end. The airplane continued over an embankment and collided with terrain, which resulted in substantial damage to the left wing. The airplane was equipped with an Allison 250-B17F/2 engine via Supplemental Type Certificate on February 15, 2003. The engine was examined on the airframe before being removed for a detailed examination. Examination of the engine did not find any anomalies that would have contributed to the loss of engine power. The propeller overspeed governor and propeller power turbine governor were also tested. No anomalies were detected with either governor.
