NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane was climbing through 4,000 feet msl when the engine rpm increased, and the engine oil pressure dropped to zero. The pilot reported the situation to departure control and they vectored the airplane toward the nearest airport. The engine began to shake violently for about 15 seconds and then seized. The pilot elected to land in a field short of the runway. The airplane touched down approximately wings level with the landing gear retracted, and 'slid through the field for roughly 125 feet' before coming to a stop. The pilot stated he did not lower the landing gear due to the need for altitude and airspeed to reach the field. Examination of the engine revealed that the #4 connecting rod was sticking out of the crankcase. Further examination revealed that an oil cooler line had ruptured. The last annual inspection was completed on March 19, 2000, eight flight hours prior to the accident.

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

Engine seizure due to the rupture of an oil cooler line.
