NTSB Factual Report

According to the pilot, he was practicing an aerial application flight over a field and successfully sprayed two lines. Then, while turning back to spray a third line, the pilot “pitched the airplane too nose high." The airplane then "lost speed" and subsequently impacted the ground on a 030-degree heading. Winds, recorded at an airport approximately 1 mile from the accident site, about the time of the accident, were from 150 degrees true at 3 knots. No mechanical anomalies were noted with the airplane.

NTSB Probable Cause

The pilot's failure to maintain adequate airspeed while maneuvering, which resulted in an aerodynamic stall.
