NTSB Factual Report

The pilot was performing an aerial application of a field when he executed a turn to line up for the next spray pass. During the turn, the airplane airspeed slowed, and the airplane stalled. The airplane impacted the field and sustained substantial damage to both wings. The pilot stated that he should have discontinued the turn rather than attempt to align the airplane for the next spray pass.

NTSB Probable Cause

The pilot's failure to maintain an adequate airspeed while maneuvering, which resulted in a stall during the aerial application.
