THE ACCIDENT AIRPLANE VEERED OFF THE RUNWAY AND NOSED OVER IN RAIN SOFTENED SOD WHILE ATTEMPTING A TAKEOFF. THE PLT RELATED THAT IT WAS HIS IMPRESSION THAT HE DID NOT HAVE COMPLETE CONTROL OF THE AIRPLANE DURING THE LATTER PORTION OF HIS TAKEOFF ROLL AND HE DECIDED TO ABORT THE TAKEOFF BECAUSE HE COULD NOT MAINTAIN HIS DESIRED TRACK DOWN THE RUNWAY. THE AIRPLANE THEN LEFT THE RUNWAY AND NOSED OVER. HE ALSO SAID THAT A POST ACCIDENT INSPECTION REVEALED NO MECHANICAL DEFECTS IN THE AIRPLANE.
