Canadair CL-44/CC-106 Yukon, a Canadian turboprop airliner and cargo aircraft based on the Bristol Britannia, developed and produced by Canadair in the late 1950s and early 1960s.

The Canadair CL-44/CC-106 Yukon, a Canadian turboprop airliner and cargo aircraft based on the Bristol Britannia, was developed and produced by Canadair in the late 1950s and early 1960s.  Although innovative, only a small number of the aircraft was produced for the RCAF (as the CC-106 Yukon), and for commercial operators worldwide (as the CL-44).  The aircraft is named after the Canadian territory of Yukon, and was given to the aircraft by the RCAF's Chief of the Air Staff Air Marshal Hugh Lester Campbell OBE, CD.

Canadair began work on a long range transport primarily intended to provide personnel and logistics support for Canadian Forces in Europe. In January 1957, Canadair received a contract for eight aircraft, later increased to 12. The RCAF designation for the new design was CC-106 Yukon, while the company's civilian variant was known as the CL-44-6. In company parlance the CL-44 was simply "the Forty-Four." The RCAF specified the CL-44 to be equipped with Bristol Orion engines. When the British Ministry of Supply canceled the Orion program, the RCAF revised the specifications to substitute the Rolls-Royce Tyne 11. The CL-44 fuselage was lengthened, making it 12 ft 4 in (3.75 m) longer than the Britannia 300 with two large cargo doors added on the port side on some aircraft, while the cabin was pressurized to maintain a cabin altitude of 2,400 m at 9,000 m (30,000 ft). The design used modified CL-28 wings and controls. The Yukon could accommodate 134 passengers and a crew of nine. In the casualty evacuation role, it could take 80 patients and a crew of 11.

The rollout of the Yukon was a near-disaster because the prototype could not be pushed out of the hangar since the vertical fin could not clear the hangar doors. The first flight took place 15 November 1959 at Cartierville Airport. During test flights many problems were encountered, from complete electrical failure to engines shaking loose and almost falling off. Rolls-Royce had problems delivering engines, resulting in the sarcastically-named "Yukon gliders" being parked outside Canadair as late as 1961.

Initially, the CL-44-6 was produced for the RCAF as the CC-106 Yukon. Once initial problems were resolved, in RCAF service the Yukon performed well and in December 1961, a Yukon set a world record for its class when it flew 6,750 mi (10,860 km) from Tokyo to RCAF Station Trenton, Ontario, in 17 hours, three minutes at an average speed of 400 mph (640 km/h). Later, a Yukon set a new record staying airborne for 23 hours and 51 minutes. These records were unbroken until bettered by the Boeing 747SP in 1975. By the time of their retirement, Yukons had flown 65 million miles, 1.5 billion passenger miles and 360 million ton-miles.

On the cargo aircraft variant CL-44D4 the entire tail section hinged. It could be opened using hydraulic actuators to load large items quickly. An inflatable seal at the hinge-break enabled cabin pressure to be maintained, and eight hydraulic-operated locks assured structural integrity. The tail could be opened from controls within the tail in 90 seconds. The flight controls at the joint were maintained by a system of push pads. Wikipedia
