Aircraft Accident/Incident Report
Stanfield, Arizona 85272
Tuesady, August 24, 1999 1:30 MST
NTSB Narrative Summary Released at Completion of Accident
The pilot said that the engine temperature reached red line earlier than usual during the takeoff ground roll on the 2,200-foot-long runway, and that he reduced the throttle somewhat to keep from exceeding takeoff limitations. He reported that the acceleration seemed sluggish and the airplane overran the runway end and collided with a berm. The pilot reported that the airplane was becoming airborne right at the time of impact. Three ground crewmembers that witnessed the accident reported that they didn't notice any unusual noises from the engine, but they noted that it seemed like a 'slow acceleration.' The pilot stated that he had not experienced any mechanical problems with the aircraft prior to the accident, and reported that the engine sounded normal during the takeoff roll. He further reported that the accident could have been prevented by taking off with a lighter load.
NTSB Probable Cause Narrative
The pilot's delay in aborting the takeoff after noting sluggish acceleration during the takeoff roll, which resulted in a runway overrun.
