The NTSB's narrative final · quoted from the NTSB record
The pilot loaded the aircraft with 200 lbs. of insecticide and 60 gals. of fuel prior to departure. His first pass of spraying the field was successful, but he did not maintain as fast an airspeed on his second pass. As he was rolling out from his second pass, he pulled up over a 50 foot bluff and the aircraft 'mushed in or sank.' There were ridges on both sides, preventing the aircraft from turning. He attempted to fly up the ridge, but the aircraft stalled, impacting the ridge and slid approximately 100 feet before coming to a stop.
