AN FAA AVIATION SAFETY INSPECTOR STATED THAT A TAKEOFF SHOULD NOT BE ATTEMPTED IF THE TAKEOFF DISTANCE CANNOT BE DETERMINED BY THE CHARTS. AFTER THE ACCIDENT THE ENGINE WAS TEST RUN THE THE MIXTURE WAS LEANED USING THE PILOTS TECHNIQUE.

TAKEOFF ROLL WAS LONGER THAN USUAL & THE ACFT WOULD NOT CLIMB ABOVE 200 FT. THE TERRAIN WAS RISING TO THE SOUTH SO THE PILOT MADE A FORCED LANDING IN A PLOWED FIELD ONE MILE SOUTH OF THE ARPT.
