Analysis

The pilot of an aerial application helicopter reported that after spraying a field he noticed that he missed a portion of the field. The pilot further reported that he maneuvered at a low altitude to the south end of the field, made a quick right turn to the north, dove into the field at approximately 45 knots, flew into his own vortices, and impacted the terrain.

The helicopter sustained substantial damage to the fuselage.

The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
