Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

The 325-hour pilot was testing the calibration of the spray function on a single-engine agricultural airplane by making low passes over a field adjacent to a runway. Upon completion of the first spray pass, the pilot increased his pitch angle, and entered a left turn. During this time, a witness observed water being dumped from the airplane. The airplane continued to pitch up, then it rolled to the right, and impacted the ground nose first. Due to impact damage, it could not be determined if there was a mechanical problem with the dump valve. However, the dump valve was found in the full open position and the stop for the handle was in a position that would have kept it from being returned to the closed position.

NTSB Probable Cause Narrative

A loss of aircraft control for undetermined reasons.
