The NTSB's narrative final · quoted from the NTSB record
According to the pilot's accident report, he had made a conventional 3-point landing. The airplane had rolled about 75 to 100 feet when the "engine sagged from the right front and rolled underneath [the airplane]." The pilot thought he had run over something on the runway, but he had actually "bounced over the engine." The airplane nosed over and slid to a stop. The upper wing, fuselage, and vertical stabilizer were crushed. The pilot said the two top bolts and welds on the homemade engine mount broke and the engine separated from the airframe because it had not been "adjusted for the weight of the Jacobs engine." The airplane had accumulated 16 hours of a 40-hour test phase.
