The NTSB's narrative final · quoted from the NTSB record
THE PILOT ABORTED THE TAKEOFF AFTER REACHING 60 KNOTS BECAUSE HE DID NOT THINK HE COULD SAFELY TAKEOFF IN THE DISTANCE REMAINING. HE WAS UNABLE TO STOP THE AIRPLANE ON THE REMAINING RUNWAY. THE AIRPLANE SUBSEQUENTLY STRUCK A DITCH. THE RUNWAY HAD A CREST IN IT AND RAN UPHILL FOR THE FIRST 1,800 FEET OF THE 2,500 FEET AVAILABLE. THE ELEVATOR TRIM WAS FOUND IN THE FULL NOSE DOWN SETTING. IT WAS THE PILOT'S FIRST EXPERIENCE AT THE ACCIDENT AIRPORT AND HIS FIRST FLIGHT IN THE ACCIDENT MAKE AND MODEL WITH FOUR PEOPLE ONBOARD
