Sequence of Events
According to witness reports, the aircraft climbed to approximately 250 feet above ground level after takeoff. During the climb, the engine sounded as if it abruptly lost power. Subsequently, the aircraft's wings began to roll left and right, and the aircraft appeared to initiate a left turn. No abrupt pitch-up maneuvers were observed. The aircraft then stalled, entered a spin to the left, and descended, crashing onto a city street. Following the crash, a car collided with the aircraft.
Postcrash Examination
Postcrash examination of the aircraft revealed no evidence of precrash engine malfunction. The engine tachometer was found indicating 2100 RPM. Examination of the propeller showed damage consistent with rotation under high engine power at the time of ground impact. Additionally, three propeller slash marks were found on the ground, further supporting the conclusion that the engine was producing high power at impact.
Witness Observations
Witnesses provided key details about the aircraft's behavior in the final moments of flight. The initial climb to 250 feet was followed by an abrupt change in engine sound, suggesting a loss of power. The subsequent rolling motion and left turn preceded the stall and spin. No witnesses reported any abrupt nose-up pitch changes.
