Aircraft Accident/Incident Report

Catoosa, Oklahoma 74015
Saturday, September 26, 1998 8:53 CDT

NTSB Narrative Summary Released at Completion of Accident

According to law enforcement personnel who responded to the accident site, the airplane 'stalled and crashed while simulating aerial application maneuvers over a soy bean field.' The 40 year old pilot, who was occupying the front seat of the airplane, told the ambulance attendant that the airplane 'entered a spin and he was unable to recover due to the airplane's low altitude.' Law enforcement personnel reported that the airplane impacted the ground in a right turn in a nose low attitude. The 265 hour pilot graduated from the operator's agricultural pilot training course 8 months prior to the accident.

NTSB Probable Cause Narrative

The pilot's failure to maintain control of the airplane resulting in an inadvertent stall.
