Accident Investigation Report: Pennsylvania-Central Airlines Corp., Washington, D.C., September 12, 1946

NX-91068, a Douglas C-54, was landed safely at Washington National Airport, Washington, DC at 1342 EST, September 12, 1946, following a fire which originated in flight in the No. 4 engine. After having been brought to a stop, the aircraft was extensively damaged by the fire which spread throughout the structure. Minor injuries were sustained by the crew during evacuation of the aircraft. The Civil Aeronautics Board determined 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.
