The Canadair CL-66 was a turboprop version of the civilian Convairliner. The CC-109 Cosmopolitan or "Cosmo" in RCAF service became the standard VIP aircraft as well as replacing the Douglas DC-3 Dakota and the North American B-25 Mitchell in light transport duties. After a lengthy career stretching into the 1990s, the CC-109 was replaced by the CC-142 Dash 8 and CC-144 Challenger.

[edit] Design and development

With the close of production of the Convair CV440 in San Diego, Canadair acquired the rights to the design along with the jigs, tooling and even three unsold 440s. With the availability of a Napier Eland turbo-prop conversion, the re-engined CV-440s became the CV-540, an all-cargo variant.

In 1958, the RCAF wanted to replace their aging C-47 Dakotas with a turbo powered aircraft. Their choice was the Vickers Viscount, but the Canadian government decided against this aircraft. Instead, Canadair offered a series of CV-540 variants powered by Napier Eland turbo-props. The project was given the number CL-66 and three versions were considered. The CL-66A was to be a 48/64 passenger aircraft. The CL-66B designed to be a cargo/passenger configuration with a payload of 14200 lb. The CL-66C instead of being built by Canadair used the Convair-built 440s, having only their new engines fitted at Canadair.

The first CL-66 to fly was a “C” version with its first flight in February 1959; the CL-66B had its first flight in January 1960. No “A” versions were built.

[edit] Operational service

Canadair was not able to get contracts from any major airline for the CL-66. It was too expensive and other similar types had better performance. The two aircraft, both of them CL-66Cs, that had been used for extensive sales demonstrations, were sold to the local carrier Quebecair. The RCAF took ten aircraft, mainly Bs. The Eland, however,did not meet the expected performance; consequently, the RCAF re-engined eight remaining airframes in 1966-1967, installing Allison T-56 engines. The Eland then slipped into oblivion.

No. 412 Squadron at CFB Ottawa (S), or "Uplands" flew the "Cosmo", from 1960 to 1994 as VIP transport. The Cosmopolitan aircraft were also deployed to Europe for Canadian NATO contingent support as well as to the US in support of Canadian NORAD operations.
