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

The pilot reported that during an approach to land, he initiated his flare over a river. He reported the aircraft 'encountered a severe downdraft' and that 'elevator back pressure failed to stop (the) rapid descent.' The accompanying flight instructor reported the pilot's approach angle 'was a little bit high' and that he observed the pilot 'slamming back on the control wheel just before touchdown.' The aircraft's right main landing gear impacted rapidly upsloping terrain just short of the runway threshold; both main gear collapsed shortly thereafter. The aircraft then skidded down the runway approximately 750 feet on the nose wheel and collapsed main gear.
