Authorities are investigating a report of a small plane down in Washington's Hood Canal, a narrow waterway in Puget Sound.

Central Kitsap Fire and Rescue says one of its boats located a debris field Monday in the area where the aircraft is believed to have gone down. It says the U.S. Coast Guard is sending two vessels to the area to assist.

Kitsap County sheriff's Sgt. Ken Dickinson says callers reported what appeared to be a plane in distress at about 1 p.m. and that they saw debris in the water.

He says a Coast Guard helicopter spotted the debris field at about 2:15 p.m. in a cove near the town of Seabeck, which is on the Kitsap Peninsula west of Seattle.

Dickinson says they're searching the debris.
