At about 12:35 EST, a Mooney M20M was damaged when it made a forced landing shortly after takeoff from Edward F. Knapp State Airport. The pilot was not injured. The pilot said that a few minutes after takeoff the engine stopped developing full manifold pressure, then the engine lost all oil pressure. The engine began to vibrate, so the pilot shut it down and landed in a field. Examination showed the engines crankshaft seal had been blown outward. Ice was observed in the engine crankcase breather line.
