Narrative:

After a normal runup was performed, aircraft was cleared to takeoff with a north departure. At approximately 200 ft AGL, engine dramatically lost power. Problem sounded like full starvation. In the short time available, we tried to troubleshoot for this problem. This was to no avail and I prepared for a forced landing. Aircraft was landed in a field with no damage or injury to passengers approximately 1 mi north of centennial airport. Problem sounded like fuel contamination but preflight check and a check of the sumps after the forced landing showed no signs of contamination. Callback conversation with reporter revealed the following information. The small aircraft landed without any damage in 'uphill prairie.' the aircraft was towed back to the airport and was runup. The engine ran 'ok.' a trace of water was found in the fuel sump, but none was found in the tanks. An emergency airworthiness directive was published within a week of this incident dealing with a series of stuck carburetor floats on this type aircraft. The carburetor was sent off to overhaul and no word has been returned regarding the outcome of the overhaul.

Title: AN SMA LANDED OFF FIELD IMMEDIATELY AFTER TKOF WITH A LARGE LOSS OF PWR.

Narrative: AFTER A NORMAL RUNUP WAS PERFORMED, ACFT WAS CLRED TO TKOF WITH A N DEP. AT APPROX 200 FT AGL, ENG DRAMATICALLY LOST PWR. PROBLEM SOUNDED LIKE FULL STARVATION. IN THE SHORT TIME AVAILABLE, WE TRIED TO TROUBLESHOOT FOR THIS PROBLEM. THIS WAS TO NO AVAIL AND I PREPARED FOR A FORCED LNDG. ACFT WAS LANDED IN A FIELD WITH NO DAMAGE OR INJURY TO PAXS APPROX 1 MI N OF CENTENNIAL ARPT. PROBLEM SOUNDED LIKE FUEL CONTAMINATION BUT PREFLT CHK AND A CHK OF THE SUMPS AFTER THE FORCED LNDG SHOWED NO SIGNS OF CONTAMINATION. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. THE SMA LANDED WITHOUT ANY DAMAGE IN 'UPHILL PRAIRIE.' THE ACFT WAS TOWED BACK TO THE ARPT AND WAS RUNUP. THE ENG RAN 'OK.' A TRACE OF WATER WAS FOUND IN THE FUEL SUMP, BUT NONE WAS FOUND IN THE TANKS. AN EMER AIRWORTHINESS DIRECTIVE WAS PUBLISHED WITHIN A WK OF THIS INCIDENT DEALING WITH A SERIES OF STUCK CARB FLOATS ON THIS TYPE ACFT. THE CARB WAS SENT OFF TO OVERHAUL AND NO WORD HAS BEEN RETURNED REGARDING THE OUTCOME OF THE OVERHAUL.
