Aircraft Accident/Incident Report

Durango, Colorado 81301
Sunday, September 27, 1998 17:30 MDT

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

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.
