Aircraft Accident/Incident Report
Arriba, Colorado 80804
Thursday, May 5, 2011 17:30 MDT
NTSB Narrative Summary Released at Completion of Accident
The pilot completed an aerial application portion of his flight and departed from the work area. The airplane collided with the ground at a high speed in a flat, open field about 7 miles from the work area. The pilot sustained serious injuries and was unable to recall any of the events preceding the accident. Postaccident examination of the airplane did not identify any preimpact abnormalities with the airframe or engine. The airplane’s three-bladed propeller displayed signatures that were consistent with the engine producing power at the time of impact. Data recovered from an on-board GPS unit tracked the airplane from departure to the accident site. The data showed that, during the final minute of the flight, the airplane’s airspeed increased and its altitude decreased. The flight profile is consistent with a controlled flight into terrain (CFIT) for undetermined reasons.
NTSB Probable Cause Narrative
The pilot’s controlled flight into terrain for undetermined reasons.
