The plane crashed on the side of a runway and city spokesman Marc Mortenson said the 9 a.m. crash delayed the arrival of an early afternoon arrival of a SkyWest Airlines flight from Phoenix by 15 minutes.

The pilot's identity was not released.

Federal Aviation Administration spokesman Ian Gregor said the FAA and the National Transportation Safety Board will investigate the crash.

St. George Airport is 275 miles (443 kilometers) south of Salt Lake City.
