On September 19, 2020 at 0945 mountain daylight time, an experimental amateur built Vans RV-4 airplane, N250LB, was substantially damaged when it was involved in an accident near Clovis, New Mexico. The pilot was seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

According to a witness, the airplane began a ground roll to the south into the wind. The airplane lifted off the ground about midfield and immediately transitioned into a climb. As it reached about 100 ft above ground level, the airplane rolled to the right until it was inverted and then disappeared from the witness’ view. The witness reported that the engine sounded smooth and continuous during the accident flight.

A preliminary examination of the accident site by a Federal Aviation Administration (FAA) inspector revealed that the airplane came to rest inverted about 800 ft beyond the end of the departure runway. According to the FAA, the impact signatures showed that the airplane initially impacted the ground at a shallow angle in the upright position, overran a cattle guard and subsequently came to rest inverted. Photographs furnished by the witness showed substantial damage to the fuselage and wings. The FAA inspector reported that flight control continuity was established from the cockpit to the ailerons, rudder, and elevator.
