Federal investigators are probing the fuselage of a seaplane that crashed Monday off Miami Beach, Florida, killing at least 19 people on board.

Salvage crews are trying to recover the cockpit voice recorder to help determine the cause of the crash. On Tuesday they pulled the plane's right wing out of the coastal waters. But Mark Rosenker, acting chairman of the National Transportation Safety Board, said raising the body of the plane is a much more delicate operation.

He said a full investigation of the crash is expected to take nine months to a year.

Crews are also searching for the remains of one last missing passenger, after recovering 19 bodies. The crash occurred shortly after the plane took off from Miami, on its way the Bahamian island of Bimini.
