NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
After the pilot taxied onto the runway for departure, he set the elevator trim wheel 1/2 inch nose down, announced his departure, and applied full power. He reported that he 'felt nose-down pressure from the beginning of the takeoff roll.' As the airplane accelerated, the pilot 'wound off the trim' and at 55 knots, the airplane rotated. The pilot stated that immediately after takeoff, the airplane dove toward the runway. It struck the runway and bounced twice. The airplane then experienced a 'small bounce', and landed on the main gear. The pilot stated that he experienced no flight control difficulties prior to the accident, and reported that the accident could have been caused by many possibilities, including, '...a stall, excessive nose-down trim, or a relaxed yoke.' Additionally, the pilot stated his normal procedure for takeoff was to apply about 1/2 inch of nose-down trim, to 'keep the airplane on the runway.' After the accident, the elevator trim wheel was rotated without restriction, and examination of the airplane revealed no pre-impact failure of the flight controls.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's failure to maintain control of the airplane which resulted in an inadvertent stall. A factor in the accident was the pilot's use of excessive nose-down elevator trim. Full narrative available
