Narrative:A no. 4 engine fire forced the crew to land immediately at Washington-National. The fire was fed by fuel and oil escaping from melted and burned fuel and oil line connections. The engine separated from the wing just prior to touchdown.
PROBABLE CAUSE: "The Board determines that the probable cause of this accident was the failure in the No. 4 engine of the exhaust valve of the No. 2 cylinder and the exhaust connection of the No. 1 cylinder which resulted in fire in flight. A contributing factor was the inadequacy of the seal between the firewall and nacelle skin and between individual cowl panels which permitted the fire eventually to reach Zone 3 and to become uncontrollable."
