Saturday, June 4, 1994 15:20 PDT

NTSB Narrative Summary Released at Completion of Accident

In a statement to responding county sheriff's deputies, the pilot said that while returning to the airport he experienced a compelling physiological need and landed the aircraft in an open dirt field. During the takeoff ground roll, the aircraft encountered soft soil and nosed over. In his written statement to the Safety Board, the pilot reported that during the takeoff ground roll just prior to rotation, the engine started to run rough. The pilot reported that he aborted the takeoff and could not stop prior to encountering a plowed area of the field. The engine was removed from the aircraft and taken to an engine repair facility. The engine was installed in a test cell, where it started on the first attempt and ran smoothly throughout all normal power ranges.

NTSB Probable Cause Narrative

the pilot's selection of an unsuitable field for an off-airport landing and attempted takeoff.
