The NTSB's narrative final · quoted from the NTSB record
The pilot was attempting a short field landing and allowed the airspeed to dissipate too soon. The airplane entered a stall/mush condition and landed hard. The force of the landing bent the engine mounts and broke the wings. The pilot reported that he had not experienced any mechanical problems with the aircraft. The airplane was equipped with vortex generators on the wings and vertical stabilizer, which, according to the STC developer, reduces the stall, approach and Vmca airspeeds by at least 10 knots. The various reference speed reductions were never approved for inclusion as a supplement to the Pilot's Operating Handbook (POH). The STC developer said that pilots were supposed to use the original speeds and limitations in the POH. The pilot said he was using an approach speed derived from a sales brochure from the STC maker. The pilot stated that the accident could have been prevented by maintaining 'greater speed.'
