Narrative:The Super Constellation departed Gander at 17:09 GMT for a military (MATS) charter flight to Frankfurt. Three hours later, at FL210 a fire developed in the no. 3 engine, which was shut down and the propeller feathered. The no. 1 engine oversped 5 minutes later when the flight engineer closed the no. 1 engine firewall shut-off valve in error. The crew were not able to restart the engine, and wanted to divert to Shannon with METO power on the no. 4 engine and reduced power on engine no. 2. The no. 2 engine lost power and finally failed, forcing the crew to carry out a ditching. The left wing broke off, but the fuselage remained intact. The cabin filled with water fast and the aircraft sank nose first in about 10 minutes.
PROBABLE CAUSE: "The failure of two of the aircraft's four engines, and improper action of the flight engineer which disabled a third engine thereby necessitating a ditching at sea."
