The NTSB's narrative final · quoted from the NTSB record
The certificated commerical pilot loaded the accident airplane's hopper tank with about 300 gallons of diesel fuel. While departing runway 31, about 75 feet above the runway, the pilot reported that the engine began to lose power. He said that emergency engine procedures did not restore power. The airplane landed on the runway, about 100 feet from the runway threshold, continued off the end of the runway, and collided with a stand of trees. A witness to the accident reported that the accident airplane's engine appeared to be operating normally as the airplane climbed to about 50 feet above the runway, and eventually settled back onto the runway. The FAA inspector, in conjunction with the accident pilot, estimated the gross weight of the accident airplane, during the accident flight, to be about 700 pounds over of the maximum allowable gross weight.
