List of accidents and incidents involving the Douglas DC-4



The Douglas DC-4 is a piston-engine airliner and transport aircraft built by the Douglas Aircraft Company from 1942 to 1947. The type was originally designed as a commercial airliner, but until the end of World War II, all were built as military transports. After the war, many of these military aircraft were converted into commercial transports. Including military versions, more than 1200 DC-4s were built; a few are still flying today.

The DC-4 was known as the C-54 Skymaster in United States Army and Air Force service. In United States Navy service prior to 1962 it was known as the R5D; that year all U.S. Navy variants were also designated as the C-54.

1940s

At the time this was the deadliest airliner crash in United States history. The cause of the dive was never determined.

1950s

 * 22 January 1950: An Air France DC-4-1009 (F-BBDB) burned out in a hangar during maintenance at Orly Airport.

The aircraft descended over mountainous terrain and later struck the mountain.


 * 1950 Air France multiple Douglas DC-4 accidents: On 12 June, an Air France DC-4 (F-BBDF, Ciel de Picardie) on a flight from Saigon to Paris crashed in the Arabian Sea while on approach to Bahrain Airport, killing 46 of 52 on board. Two days later, on 14 June, another Air France DC-4 (F-BBDM, Ciel de Gascogne) also crashed in the Arabian Sea while on approach to Bahrain Airport, killing 40 of 53 on board. This aircraft was operating on the same flight route as F-BBDF.
