The commercial pilot, the sole occupant, was fatally injured; the airplane sustained substantial damage. The local agricultural flight departed from Farm Air Service facility, Sacramento, California. Visual meteorological conditions prevailed, and no flight plan had been filed.

Witnesses saw the airplane make a low pass across a field, make a hard banking turn to return towards the field, and impact the ground.

The operator reported that the pilot had departed from their base of operations 10 miles south of the accident site to apply 1,000 lbs of fertilizer to a rice field.
