Location: Big Piney, WY
Accident Number: WPR20LA054
Date & Time: 12/30/2019, 1445 MST
Registration: N43866
Aircraft: Mitsubishi MU2B
Injuries: 4 None
Flight Conducted Under: Part 91: General Aviation - Personal 

On December 30, 2019, about 1445 mountain standard time, a Mitsubishi MU-2-60 airplane, N43866, was substantially damaged during a runway excursion at the Miley Memorial Field Airport (BPI), Big Piney, Wyoming. The private pilot and 3 passengers were not injured. The airplane was registered to Pickett Aviation, LLC. and operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed, and an instrument flight rules flight plan was filed for the cross country flight which departed the North Platte Regional Airport Lee Bird Field (LBF), North Platte, Nebraska, at 1245.

The pilot reported that the approach was normal, and he did not experience any issues when the airplane made contact with the runway. However, as he moved both throttles to the beta position, it appeared that the left propeller went to beta position while the right one did not. This resulted in a course deviation about 30°- 35°. An attempt to correct the drift with the nose gear control was unsuccessful. The airplane departed the runway and began to turn which led to the right main landing gear separation, collision of the right wing with terrain and the right wing tip separation. The airplane came to rest left of the runway with the nose of the airplane oriented towards the approach end. The airplane was relocated to a secure facility for further examination.
