Analysis
The non-certificated pilot stated that during takeoff the airplane did not have sufficient speed and did not feel right at a point on runway 36 where the airplane should have lifted off. The pilot then attempted to abort the takeoff, but the airplane overran the runway and nosed over. The airplane empennage was deformed upward and the left wing was deformed downward, resulting in substantial damage. The pilot did not have a pilot certificate and his last airman medical was dated December 18, 1999. The pilot did not have a pilot logbook nor any record of training, currency, or proficiency. Inspection of the airplane revealed that it was over gross weight at the time of the accident.
