Aircraft Accident/Incident Report
Waunakee, Wisconsin 53597
Saturday, July 31, 2004 19:30 CDT
NTSB Narrative Summary Released at Completion of Accident
The airplane stalled while on short final approach, which resulted in a hard landing. The pilot reported that when he turned onto final approach the airplane was positioned about 500 feet above ground level (agl) with an airspeed indication of 80 miles/hour. The pilot stated that he noticed the airplane was too high while he crossed-over the approach end of the runway and that the "airspeed was at stall [speed]." The pilot stated he responded by lowering the aircraft's nose and increasing engine power. The pilot reported the increase of engine power "did not respond until nearly on the runway." The pilot stated the airplane "landed hard" and the main landing gear collapsed.
NTSB Probable Cause Narrative
The pilot's failure to maintain proper airspeed during final approach, which resulted in the inadvertent stall/mush at a low altitude and subsequent hard landing. A factor to the accident was the pilot's unsuccessful remedial action to the encountered stall/mush at a low altitude.
