MOORHEAD, Minn. (AP) — The Federal Aviation Administration and National Transportation Safety Board will investigate the cause of an airplane crash landing near the Moorhead airport.

The twin engine turboprop was approaching the airport Wednesday evening when it ended up in a farm field a short distance from the runway.

Clay County Sheriff’s Lt. Mark Empting says there were seven people aboard the plane, including the pilot. He says some of the passengers were treated at the scene for minor injuries. The pilot was taken to a Fargo, North Dakota, hospital with minor injuries.

Empting tells KFGO radio that it was foggy at the time but it’s too early to speculate on what happened.
