THE PILOT STATED THAT HE TOOK OFF ON RUNWAY 30 AFTER A GROUND ROLL OF ABOUT 200 FT, STARTED TO CLIMB, AND AT ABOUT 75 FT NOTICED HE WAS FLYING TOO SLOW, HE FELT A BUFFET AND PUSHED AND STICK FORWARD AND REDUCED POWER TO PREVENT A POWER ON STALL. THE AIRCRAFT FELL TO THE GROUND AT ABOUT 4 DEG NOSE DOWN ATTITUDE.
