AIRPORT EMPLOYEES OBSERVED THE AIRCRAFT TAKEOFF ON RUNWAY 25 AND ACHIEVE AN ALTITUDE OF ABOUT 50 FEET ABOVE THE GROUND. THE WITNESSES REPORTED THAT THE AIRCRAFT SEEMED TO BE 'STRUGGLING' AS IT FLEW DOWN THE RUNWAY AT THAT ALTITUDE. ABOUT ONE HALF MILE BEYOND THE END OF THE RUNWAY THE AIRCRAFT WAS OBSERVED TO BEGIN A LEFT TURN, STALL, THEN FALL OFF ON THE LEFT WING AND HIT THE GROUND NOSE FIRST.

FACTORS IN THE ACCIDENT WERE THE HIGH DENSITY ALTITUDE CONDITION AND THE PILOTS LIMITED TOTAL EXPERIENCE.
