Crews are expected to retrieve a plane that made an emergency landing in Mount Pleasant, South Carolina. PA-60 AEROSTAR, N3643D

Sea Tow officials say they expect to remove the plane from the marsh at some point on Monday. Pilot Terry Huenefeld was able to safely land the twin engine piper plane just off Horlbeck Creek on Thursday.

An FAA spokesperson says their investigators will help gather information to provide to the National Transportation Safety Board, and then the NTSB will determine what caused the emergency landing.

Another big concern of authorities on the scene was whether or not the plane was leaking any fuel. The Coast Guard was called out to control any spills.

"With the amount of fuel on board I don't think it would be very detrimental to marine life, but any fuel can't be good, so the coast guard is here to prevent that," Sea Tow assistant manager Doug Miller said.
