The NTSB's narrative final · quoted from the NTSB record

The pilot reported in a telephonic interview that he and his son were on a local sightseeing flight operating approximately 1,000 feet above ground when the aircraft encountered a strong downdraft. Concerned that the aircraft might make contact with terrain, the pilot maneuvered over a dirt road. Although the pilot reported no mechanical problem with the aircraft or its powerplant, the aircraft continued to descend until touchdown on the road. During the landing roll, the right main landing gear and right wing impacted a fence post and the right wheel separated from the strut. The aircraft then veered right off the road nosing over as it passed into a ditch.
