The Pilot Reported This Was The First Flight Of The Experimental Airplane
On July 1, 2023, about 0853 central daylight time, a Berkut 540 airplane, N567JS, was substantially damaged when it was involved in an accident near Cedar Rapids, Iowa. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 test flight. The pilot reported this was the first flight of the experimental airplane. After takeoff, the pilot proceeded east of the airport and was cleared to 5,000 ft mean sea level (msl). However, upon reaching 3,400 ft msl, the airplane entered a gradual descent, and the pilot subsequently realized that the engine had lost partial power.
