Analysis

The plt was positioning the acft for swath runs when it crashed into rising terrain on the side of a hill next to a valley. The plt had planned to make swath runs over an orchard in the valley. During impact, he received serious head injuries & could not recall the circumstances of the mishap. However, he was able to exit the acft before fire had spread to the cockpit. Witnesses about 1 mi from the crash site reported hearing a steady engine sound until the acft impacted. The acft remained intact & the ground scars showed that it had moved about 6 ft forward & 4 ft left after impacting.
