Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

The pilot stated that he became airborne approximately midfield; however, "after rising a few feet, the acceleration seemed sluggish." He also stated that at midfield he "noticed a drop in power," but continued with the take off. The pilot stated that the airplane settled towards the runway, "accelerat[ed] and rose again." He stated that the stall warning horn sounded, and he "leveled in ground effect to accelerate." He maneuvered the airplane to avoid the runway end lights and a truck on the service road off the end of the runway. The airplane impacted the ground near the service road and nosed over causing substantial damage. An examination of the engine revealed no anomalies that would have precluded the engine from producing power.

NTSB Probable Cause Narrative

the pilot's failure to maintain adequate airspeed which resulted in a stall, and his failure to abort the takeoff. The loss of power for undetermined reasons is a contributing factor.
