The CL-66 was the turboprop variant of the civil Convair CV-440 passenger aircraft and was used as the CC-109 Cosmopolitan to the standard VIP aircraft of the Royal Canadian Air Force and also for light transport tasks.

History and construction

After production of the Convair CV-440 was finished in San Diego, Canadair acquired the rights to the design, including assembly devices, tools and three unsold CV-440s. Due to the availability of the Napier Eland turboprop engine, the CV-440 became the Convair 540 . Like the CV-440, the CL-66 is also equipped with a pressurized cabin .

In 1958, the RCAF wanted to replace their aging Douglas C-47 with a turboprop- powered aircraft. The Vickers Viscount was their first choice , but the Canadian government decided against this aircraft. Instead, Canadair offered a number of Convair 540 variants with the Napier Eland turboprop engine. The project was named CL-66 and three versions were developed. The first flight of the CL-66C took place on February 2, 1959, the CL-66B followed in January 1960. Not a single "A" version was built. Canadair, despite its best efforts, did not receive any airline orders for the CL-66 because it was too expensive and other manufacturers' aircraft performed better. The RCAF took over ten aircraft, mostly CL-66B. Two machines used as demonstration aircraft were sold to Quebecair .

Since the Eland engines proved to be unreliable and too weak in terms of performance, these were replaced by Allison 501-D36 propeller turbines in the machines used by the RCAF in 1966 and 67 .
