OWYHEE COUNTY - A Boise pilot died Friday in a plane crash in Owyhee County, sheriff's officials said.

The Owyhee County Sheriff's Office said 56-year-old Dean Hilde was flying a personal aircraft in the Combination area of the county - southeast of the Jordan and Pleasant Valley area - when he apparently encountered tough, windy conditions.

The plane was forced into a hillside.

Hilde was pronounced dead at the scene. His passenger, 42-year-old Gerald Bublitz of Boise, suffered serious injuries and was transported to an area hospital by air ambulance.

The Federal Aviation Administration is investigating.
