NTSB narrative
The pilot was making an aerial application run when the airplane stalled and impacted the terrain in a nose-low attitude. A witness reported seeing the airplane make its spray runs and; “nothing [appeared] out of the ordinary.” The witness, who had his back to the airplane, continued with his work then he heard a loud “pop”. As he turned around, he believed he saw a large spray of water when the airplane hit standing water. The witness also reported that the airplane’s engine noise stopped immediately, when he heard the “pop”. An examination of the engine found that the engine was producing mid-to-high power at the time of impact. Additionally, the flap jackscrew was found extended; which corresponded to a full flaps down setting. The airframe manufacturer noted that there is not an approved procedure for making application turns with flaps fully extended. The commercial pilot had a total of 356 flight-hours, of which about 70-hours were in the accident airplane. Examination of the airplane and engine did not disclose any evidence of a mechanical malfunction.
Probable cause
The pilot's failure to maintain airspeed, resulting in an inadvertent low-altitude aerodynamic stall.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2008-05-15.
