Wednesday, July 2, 2008 13:07 PDT
NTSB Narrative Summary Released at Completion of Accident
The airplane was observed maneuvering at a low altitude over a sparsely populated wooded area during daylight hours in visual meteorological conditions. There were no known witnesses to the accident sequence. Wreckage and impact signatures were consistent with level attitude, high-speed impact with trees and terrain. The wreckage debris path was about 200 feet in length and all major components of the airplane were located within the debris path. A United States Forest Service lookout tower personnel, located about 12 miles east southeast of the accident site stated that around mid day, visibility was about 1/4 to 1/2 miles with heavy smoke in the area. A local law enforcement officer reported that the day of the accident, visibility was marginal due to smoke in the area of the accident. Examination of the airframe and engine revealed no evidence of preimpact mechanical malfunction.
NTSB Probable Cause Narrative
The pilot's failure to maintain clearance with trees and terrain while maneuvering Contributing to the accident was the reduced visibility in the area due to smoke.
