The NTSB's narrative final · quoted from the NTSB record
Following three uneventful aerial application flights, the pilot removed the biplane's cockpit side windows. While completing the first pass of the fourth flight, the pilot 'noticed the plane did not perform as it had previously.' As he turned the airplane to begin the second pass, it settled into the trees bordering the field being sprayed. While in the trees, the pilot advanced the propeller and throttle controls and made an unsuccessful attempt to dump his load of herbicide. Upon reaching the edge of the trees, the pilot 'nosed the aircraft over to land in a small field before hitting the wire across the road.' As he flared to land, the airplane impacted the road embankment. Subsequently, the airplane nosed over, came to a stop in the inverted position, and began to burn. The postcrash fire consumed the fuselage, empennage, and the upper and lower right wings.
