Probable cause
Failure of the pilot to obtain or maintain adequate airspeed for a go-around (aborted landing), which resulted in an inadvertent stall/mush. The failure to attain proper runway alignment for landing was a related factor.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot said that while attempting to land, he was having trouble maintaining directional control. He said that he attempted to go-around, but lost directional control. The aircraft veered off the right side of the runway and came to rest 180 degrees from its original heading. Post-accident investigation revealed no airframe or powerplant abnormalities.
