Aircraft Accident/Incident Report

Cottonwood, Arizona 86326
Tuesady, June 23, 2009 8:30 MST

NTSB Narrative Summary Released at Completion of Accident

Witnesses reported hearing the accident airplane's engine sputter during the takeoff climb. The airplane's nose appeared to pitch down, level, then witnesses heard a high pitch revving sound emanating from the engine. The airplane rocked back-and-forth, the left wing dropped, and it entered a nose dive before impacting the ground. A postaccident inspection of the accident site revealed the airplane impacted the ground in a nose down attitude, with the propeller assembly separating from the crankshaft and becoming embedded in the hard desert dirt. An examination of the airplane and engine revealed no mechanical anomalies that would have precluded normal operation.

NTSB Probable Cause Narrative

The partial loss of engine power for undetermined reasons, and the pilot's failure to maintain an adequate airspeed, which resulted in an inadvertent stall/spin.
