Aircraft Accident/Incident Report

Brockton, Montana 59213
Monday, March 5, 2012 15:56 MST

NTSB Narrative Summary Released at Completion of Accident

Witnesses reported that the airplane made two low-altitude, 360-degree turns and then ascended rapidly followed by a descent into the ground, consistent with an aerodynamic stall. The airplane “belly flopped” on the edge of an elevated drive likely because there was insufficient altitude for the pilot to recover from the stall. The witnesses further reported that the engine sounded normal throughout the accident sequence. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. A GPS receiver was recovered from the accident; however, no data was recovered for the accident flight. Data from previous flights revealed flight maneuvers at low altitudes similar to the one described by witnesses during the accident sequence.

NTSB Probable Cause Narrative

The pilot’s failure to maintain adequate airspeed and airplane control while maneuvering at a low altitude, which resulted in a stall and subsequent impact with terrain.
