What happened
During the initial takeoff ground run, the aircraft proceeded at a low velocity, utilizing the entire 4,102-foot runway before achieving a brief period of flight. During this sequence, the left wing descended and made contact with overhead power lines. Following this impact, the aircraft crashed onto a highway, where it collided with a motor vehicle.
There were two occupants on board the aircraft at the time of the accident, both of whom sustained injuries.
Findings
Post-accident investigations involving a metallurgical teardown of the two turbochargers located in the left engine revealed significant issues. The examination found evidence of extreme wear within the bearings caused by the turbine wheel shafts. This degradation led to the obstruction of oil ports, which contributed to the mechanical failure during the takeoff phase.
