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

During the climb-out from takeoff at about 200 feet above ground level, the left wing just outboard of the lift strut wing attach points folded upward. The aircraft then went into a vertical descent with the wing section trailing and still attached by what one witness thought were the control cables. The aircraft continued the vertical descent to ground collision. During the descent the forward left wing lift strut separated. Sections of the left side forward and aft lift strut attach fittings and fork assemblies were examined by an NTSB metallurgist. The metallurgist reported that all fracture features and deformation were typical of overstress fractures under bending load. Historical maintenance documentation revealed that the pilot, a non-mechanic, had been doing extensive structural maintenance on the aircraft since the late 1970's, and then having a certified mechanic sign-off his work.
