On July 17, 2020, about 1345 Pacific daylight time, an experimental, amateur-built RV-8 airplane, N508CM, was substantially damaged when it was involved in an accident near Grimes, California. The private pilot and pilot-rated passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot stated that he landed the airplane at a friend’s private airstrip and taxied back to take off again. During the takeoff roll, the engine lost power and he aborted the takeoff. Later that day, the engine was examined by a mechanic, who was unable to find any anomalies. After the mechanic cleared the airplane for flight, the pilot taxied to the runway, performed two run-up checks, and then proceeded to take off. About 50 to 70 ft above ground level, the engine again lost partial power. The pilot performed a forced landing in a corn field, which resulted in substantial damage to the fuselage.

The airplane wreckage was sold before an examination could be scheduled; therefore, the reason for the loss of engine power could not be determined.
