Accident Sequence
After takeoff, the aircraft was observed to climb to approximately 400 feet above ground level (AGL). It then entered a steep left bank before leveling off and rolling out on a downwind leg that was angling toward the runway. During the downwind leg, a crewmember transmitted over the radio that they were "coming back." According to the UNICOM operator, the crewmember sounded disgusted or disappointed about something.
At or near the point where the pilot would have begun a base turn, the aircraft entered another steep left bank. Subsequently, the nose dropped and the aircraft "flew" into the ground, resulting in a post-crash fire.
Investigation Findings
No preimpact mechanical malfunction or failure was found during the investigation.
