Monday, July 10, 2006 17:35 PDT

NTSB Narrative Summary Released at Completion of Accident

While cruising en route in VFR conditions, the aircraft lost power on both engines. The pilot attempted an emergency forced landing at a nearby unpaved State airport, but after encountering a 20 mph tailwind on downwind and a 20 mph headwind on final, the aircraft impacted a tall conifer tree while about one-half mile from the approach end of the runway. The reason for the dual engine power loss was not determined.

NTSB Probable Cause Narrative

The loss of power in both engines for undetermined reasons while in cruise flight, leading to an attempted forced landing. Factors include unfavorable winds at the site of the forced landing, and trees off the approach end of the grass runway the pilot was attempting to land on.
