This is a list of aviation-related events from 1956.

## Events
### January

* Vietnam Civil Aviation is founded as the national civil aviation authority of North Vietnam, functioning as an element of the Vietnam People's Air Force responsible for state management, national defense, and commercialization of civilian air transportation. It also operates as North Vietnam's national airline, with a fleet that consists initially of two Lisunov Li-2 aircraft.

Two land safely, but the other six are destroyed in crashes in the vicinity of Swaffham and RAF Marham, with one of the pilots killed.
* February 18 – An engine fire breaks out on a Scottish Airlines Avro York just after takeoff from RAF Luqa, Malta. The aircraft stalls as the crew attempts to turn back to the airport and crashes into the ground near Zurrieq, Malta, killing all 50 people on board.

No trace of the aircraft, its three-man crew, or the cores are ever found.
** Fairey Aviation test pilot Peter Twiss sets a new airspeed record in the Fairey Delta 2, also becoming the first person to exceed 1,000 mph (1,600 km/h) in level flight. His top speed is 1,132 mph (1,822 km/h).

## Deadliest crash

The deadliest crash of this year was the 1956 Grand Canyon mid-air collision of 30 June, when a United Airlines Douglas DC-7 collided with a TWA Lockheed L-1049 Super Constellation over the Grand Canyon, Arizona, U.S., killing all 128 people aboard both aircraft. At the time, this was the deadliest accident in civil aviation history. It is also the deadliest civil aviation crash of the 1950s decade; the 1953 Tachikawa air disaster had killed 129 people but involved a military aircraft. The deadliest single-aircraft accident was Linea Aeropostal Venezolana Flight 253, a Lockheed L-1049 Super Constellation which crashed into the Atlantic Ocean off New Jersey, U.S. on 20 June, killing all 74 people on board.
