Aircraft Accident/Incident Report

Hermiston, Oregon 97838
Wednesday, December 22, 1999 19:00 PST

NTSB Narrative Summary Released at Completion of Accident

Shortly before departure, the pilot was issued an instrument flight rules (IFR) clearance from Hermiston, Oregon to Madras, Oregon. Shortly thereafter, the aircraft departed the airport from runway 04. A witness observed the aircraft enter a shallow turn to the right (south) shortly after departure, however, he lost sight of the aircraft due to trees obscuring his view. Approximately 5 minutes later, the local police received report of a downed aircraft southeast of the airport. The aircraft impacted terrain approximately 1/4 mile south of the departure end of the runway, in a right wing low attitude. The accident occurred during the hours of darkness. Low ceilings and visibility were reported at the time of the accident. No evidence was found to indicate a mechanical malfunction or failure.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance with terrain. Factors include a dark night, low ceilings and mist.
