What happened
The pilot was providing airplane rides to family and friends who had assembled at a dry lakebed. He completed two uneventful flights and then departed for a third flight from the lakebed. According to witnesses, the pilot had planned to perform a low pass over the group, and he did so just after takeoff, passing within about 50 ft directly overhead.
The entire accident sequence was captured on video. The airplane dipped its right wing as it passed over the camera position and, after the pass, continued in a climbing right turn, which progressed rapidly to almost 90 degrees of bank. The excessive bank angle resulted in the airplane exceeding its critical angle of attack and experiencing an accelerated stall at an altitude too low for recovery. The airplane then entered the initial stages of a spin before striking the ground in an almost vertical attitude.
Postaccident examination of the airframe and engine did not reveal any evidence of preimpact mechanical malfunction or failure. Although the reason for the aggressive turn could not be determined, the pilot's overflight of the group while maneuvering at low altitude is consistent with an intentionally-performed ostentatious display.
