Analysis

The pilot stated that on final approach to an off-airport landing site, about 50 feet above ground level, the airplane descended and impacted the terrain. The airplane received substantial damage to both wings and the fuselage. The pilot said there were no preimpact mechanical malfunctions with the airplane, but the wind in the area was very erratic. The pilot said the accident could have been prevented if he had made a touch-and-go landing to evaluate the wind conditions prior to landing.
