Accident
A pilot was demonstrating slow flight to a friend when the airplane experienced a loss of altitude and control difficulties. The pilot subsequently made an intentional landing on the ground.
Pilot Report
The pilot stated that he had arranged with a friend to observe the airplane in slow flight. At an altitude of 500 feet above ground level, he reduced power, added flaps, and approached his residence. While turning, a light east-northeast wind increased in velocity, causing the airplane to 'sink' and turn left. The pilot 'attempted to [turn] with no effect.' He noted that the airplane was equipped with a Wren STOL conversion, which made the controls 'very hard and slow. As [the airplane] was configured, it is very difficult whenever the wind is not on the nose.' Having lost considerable altitude and unable to maneuver due to proximity to houses and other structures, he intentionally 'put [the airplane] on the ground.' Additionally, the pilot told a sheriff's deputy that a crosswind pushed him to the ground.
Witness Observation
A witness observed the airplane descend twice 'at a rapid rate of speed,' then make 'a steep ascent back into the air.' The airplane banked 'at a 65 degree angle' and seemed to 'pivot.' The witness reported that at no time did the airplane's wings dip as if it were fighting winds.
