Aircraft Accident/Incident Report
Baker City, Oregon 97814
Friday, July 31, 1998 12:00 PDT
NTSB Narrative Summary Released at Completion of Accident
The passenger reported that as the flight continued, the clouds and fog increased around the aircraft. The passenger recalls that the pilot made altitude and heading changes to remain clear of the clouds. The passenger stated that when the accident occurred, she had her head down and eyes closed because she was airsick. The passenger stated that the engine sound never changed up to the time of the accident. Documentation of the accident site indicates that the aircraft collided with tree tops in steep mountainous terrain, and a level attitude, before coming to rest at the base of a tree stump. Wreckage was distributed along the length of the path for about 150 feet. Prior to departure, the pilot obtained a weather briefing that forecasted isolated thunderstorm activity, mountain obscuration and multiple layers of scattered and broken clouds. The pilot did not possess an instrument rating.
NTSB Probable Cause Narrative
The pilot's failure to maintain terrain clearance and inadequate in-flight planning/decision. Contributing to the accident was mountain obscuration.
