Aircraft Accident/Incident Report

Princeton, Texas 75407
Tuesady, July 16, 1996 7:20 CDT

NTSB Narrative Summary Released at Completion of Accident

While in cruise flight, the left engine propeller 'went into feather, causing the engine to stall.' The pilot's attempts to unfeather the propeller and restart the engine were unsuccessful. The airplane's single engine performance was inadequate to maintain altitude. A forced landing was made to an open field, and during the landing roll the airplane impacted a ditch. Bench testing of the left engine propeller governor revealed that the feather stop was set at 2,000 rpm instead of the specified 1,690 rpm.

NTSB Probable Cause Narrative

improper adjustment of the left propeller governor which resulted in uncommanded feathering of the left propeller. Factors were: the airplane's inadequate engine out performance and the lack of suitable terrain for the forced landing.
