Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During the aerial application flight, the pilot completed a spray run and was returning to the truck when he flew into a wire in the middle of the field, at 15 feet above the ground. Thereafter, he lost control of the helicopter and it crashed coming to rest on its right side. Prior to the mishap, the pilot had observed poles in the area, but had not observed the line that he collided with during the low altitude pass. No mechanical malfunctions or failures associated with the operation of the helicopter were indicated.
