NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

During an aerial application flight, the pilot was flying eastbound toward the morning sun. Due to the sun glare, the pilot did not see the north-south power line that crossed the airplane's flight path. The airplane subsequently collided with the power line, impacted the ground, and nosed over. The operator stated that the pilot was briefed on the location of the wire and the hazards of flight into sun prior to the flight. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain clearance with a power line. Contributing to the accident was the sun's glare.
