SHORTLY AFTER TAKE OFF, THE EXPERIMENTAL HOMEBUILT AIRPLANE WAS OBSERVED TO HAVE REACHED 150 FT AGL WHEN THE ENGINE BEGAN TO SPUTTER. THE ENGINE REGAINED FULL POWER MOMENTARILY; HOWEVER, WHEN THE AIRPLANE BEGAN A LEFT TURN, THE ENGINE SPUTTERED AND QUIT. THE AIRPLANE CONTINUED THE LEFT TURN WHICH INCREASED TO A SPIN. THE AIRPLANE THEN COLLIDED WITH THE TERRAIN IN A NOSE DOWN LEFT WING LOW ALTITUDE. DURING THE ENGINE EXAMINATION THERE WERE NO NOTED MECHANICAL FAILURES OR MALFUNCTIONS.
