The DC-6 was on its 4th attempt to land at New York-Idlewild when it struck the pier which supported the left row of runway 04 slope line approach lights. The aircraft crashed in flames and sank in Jamaica Bay. The aircraft was on a flight from Roma-Ciampino to New York via Milan, Paris, Shannon, Gander and Boston.

PROBABLE CAUSE: "An erratic approach which resulted in a descent to an altitude too low to avoid striking the pier. A contributing factor to this accident was pilot fatigue due to the particular and difficult circumstances."
