A Klamath Falls doctor made two attempts in foggy weather to land his private plane at Portland International Airport before crashing, the National Transportation Safety Board said in a preliminary report.

Dr. Richard Otoski, 62, a dermatologist, died as his single-engine Lancair Columbia 400 crashed about 8:30 a.m. Feb. 16.

After his first approach failed, the board's report said, he approached the runway again, but the plane veered to the right.

Crash and rescue personnel found Otoski's plane on a paved perimeter road about 4,500 feet from the approach end of the runway. The plane burned.

The agency said visibility was a quarter of a mile with fog and broken clouds at 900 feet.

Agency inspectors are examining the wreckage. A full report is expected in a year.
