Probable cause

The pilot-in-command's failure to maintain control of the aircraft to avoid the inadvertent entry into a stall/spin at low altitude which resulted in impact with the terrain.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot stated that the purpose of the flight was to observe crop development. The flight was conducted at a low altitude. Although the pilot does not recall the exact reason for loss of control of the aircraft, the last thing he remembers was making a left turn. A witness saw the aircraft descending wing and nose down into the terrain. The aircraft was substantially damaged and the pilot sustained serious injuries. Subsequent investigation revealed nothing of a mechanical nature that would have had a negative impact on the flight.
