SHORTLY AFTER TAKEOFF WITNESSES OBSERVED THE AIRPLANE IN A HIGH PITCH-UP ATTITUDE, YAWING LEFT AND RIGHT. ONE WITNESS, AN AIRFRAME AND POWERPLANT MECHANIC, SAID THE ENGINE SOUNDED AS THOUGH IT WAS NOT PRODUCING FULL POWER. AFTER GAINING ABOUT 100 TO 200 FEET ABOVE THE GROUND, THE AIRPLANE ROLLED INTO A 90 DEGREE BANK AND DESCENDED INTO SWAMPY TERRAIN. FLIGHT CONTROL CABLE CONTINUITY WAS ESTABLISHED. THE CARBURETOR HAD BROKEN AWAY FROM THE INTAKE MANIFOLD AND HAD BEEN SUBMERGED IN SWAMP WATER. EXAMINATION OF THE MAGNETOS REVEALED THE RIGHT MAGNETO TIMING HAD BEEN 8 DEGREES BEFORE TOP DEAD CENTER; THE MANUFACTURER'S RECOMMENDED SETTING IS 26 DEGREES BEFORE TOP DEAD CENTER. THE LEFT MAGNETO TIMING WAS SET AT THIS NUMBER. THE RIGHT MAGNETO WAS RETIMED TO THE MANUFACTURER'S PRESCRIBED SETTING. THE ENGINE RUNUP WAS ACCOMPLISHED USING ITS MAGNETOS AND A FACTORY CARBURETOR. THE ENGINE AND CARBURETOR WERE EXAMINED AT THEIR RESPECTIVE MANUFACTURERS; BOTH WERE FOUND TO OPERATE WITHIN THE MANUFACTURER'S SPECIFICATIONS.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the pilot operating the airplane with a known deficiency. A factor was the pilot not maintaining control of the airplane.
