NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot experienced a partial power failure and performed a forced landing to a field. The field was wet and soft; the nose wheel failed aft during the landing roll, and the airplane nosed over. Postimpact examination of the engine revealed that the castellated nut which held the throttle cable in place had backed off and separated from the airplane. The displacement of the throttle cable permitted the engine to transition to the idle position.

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

Improper maintenance by an unknown person and the subsequent throttle cable disconnect due to a castellated nut separation. Factors were the none suitable soft terrain for the forced landing, and the failure of the nose wheel landing gear during the landing roll.
