The NTSB's narrative final · quoted from the NTSB record

THE PURPOSE OF THE FLIGHT WAS TO PERFORM A BIENNIAL FLIGHT REVIEW. DURING THE PREFLIGHT, ABOUT 1 PINT OF FUEL WAS DRAINED FROM THE WINGS/SUMPS AND ABOUT 1/2 TEASPOON OF WATER WAS FOUND. AFTER TAKING OFF, THE POWER WAS REDUCED TO ABOUT 2500 RPM AND 25 INCHES OF MANIFOLD PRESSURE. AS THE CLIMB WAS CONTINUED, THE ENGINE LOST POWER AT ABOUT 3500 FT MSL. THE PILOTS WERE UNABLE TO RESTORE THE ENGINE POWER. THEIR EMERGENCY PROCEDURES INCLUDED THE USE OF CARBURETOR HEAT AND THE FUEL BOOST PUMP. SUBSEQUENTLY, THE AIRCRAFT FLIPPED OVER DURING A FORCED LANDING IN A SOFT FIELD. THE PILOT SUSPECTED CARBURETOR ICE, BUT THIS WAS NOT CONFIRMED. A TEARDOWN OF THE ENGINE REVEALED NO EVIDENCE OF A MECHANICAL MALFUNCTION OR FAILURE BEFORE IMPACT. THE TEMPERATURE AND DEW POINT WERE 68 AND 58 DEGREES, RESPECTIVELY.
