NTSB summary

HISTORY OF FLIGHTOn July 20, 2018, about 1604 central daylight time, a De Havilland DH112 Venom airplane, N747J, was destroyed when it was involved in an accident near Sheboygan, Wisconsin. The private pilot was fatally injured, and two people in the impacted structure were seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot was conducting a formation training flight that consisted of two airplanes; the accident airplane was in the No. 2 position and was to be staggered behind and to the right of the lead (No. 1 position) airplane. During the flight briefing, the pilot was instructed to take off 10 seconds after the lead airplane. The airplanes departed from Sheboygan County Memorial Airport (SBM), Sheboygan Falls, Wisconsin. Review of video provided by a witness showed that the accident airplane departed about 8 seconds after the lead airplane. About 6 seconds after the accident airplane lifted off, the left wing rocked downward then up, followed by the right wing rocking downward then up as the airplane returned to wings level. The accident airplane continued to climb at an angle away from the runway and the witness' position on an airport ramp. As the airplane passed the witness' position, the engine sound decreased and then rapidly increased. The video ended about 19 seconds after the airplane lifted off from the runway. The video showed that the accident airplane's flaps were extended throughout the 19-second video and that the landing gear was retracting during the last few seconds of the video. The

Probable cause

The airplane's encounter with wake turbulence from the lead airplane in the formation flight, which resulted in a compressor stall and the airplane's subsequent inability to climb.
