[edit] History
The design began life in a production requirement by American Airlines for a pressurized airliner to replace the classic Douglas DC-3. Convair's original design had two engines and 40 seats, and thus it was designated the CV-240. The first 240 flew on March 16, 1947, and production aircraft were first delivered to American on February 28, 1948. Seventy-five were delivered to American, with another fifty going to Western Airlines, Continental Airlines, Pan American Airways, KLM, and Trans-Australia Airlines.
A CV-240 was the first private aircraft used in a United States presidential campaign. In 1960, John F. Kennedy used a CV-240 dubbed Caroline during his campaign. This aircraft is now preserved in the National Air and Space Museum.

The CV-340, built for United Airlines, was lengthened to hold an additional four seats. The wings were also enlarged for better performance at higher altitudes. The CV-340 replaced the DC-3 for United. They flew 52 340s for 16 years without a fatality. An example of United's 340 was N73111. They were called "Mainliners" as other aircraft were also and N73111 was also called "Mainliner Salt Lake City" (which appeared on the nose)
The CV-440 Metropolitan had improved soundproofing and an option of weather radar.
The Convair 580 is a conversion from a Convair 340 aircraft with the original piston engines replaced with two Allison 501 D13D/H turboprop engines.
The Convair 600 is a conversion from a Convair 240 aircraft with the original piston engines replaced with Rolls-Royce Dart turboprop engines. The CV-600 first flew with Central Airlines on 30 November 1965. The CV-600 aircraft that flew with Air Metro Airways was configured as a forty passenger airliner. In August 2006 a single Convair 600 aircraft remains in airline service, with Rhoades Aviation.[1]
The Convair 640 is a conversion from either a Convair 340 or 440 with the original piston engines replaced with Rolls-Royce Dart turboprop engines. In August 2006 a total of 9 Convair 640 aircraft remain in airline service, with Rhoades Aviation (3) and C&M Airways (6).[1]
Ten CL-66 aircraft were build by Canadair in Canada, they were a version of the Convair 440 with Napier Eland turbo-props. In Canadian service they were known as the CC-109 Cosmopolitan.
The Convair 5800 is a conversion from a Convair 580 by Kelowna Flightcraft in Canada. The 5800 is a 580 stretched by 14ft 3in with the 440's original tail unit. These conversions also have a new freight door, digital avionics with EFIS and Allison 501-D22 engines.
[edit] Military variants
The CV-240/340/440 series was used by the United States Air Force for medical evacuation and VIP transport and was designated as C-131 Samaritan. The first model Samaritan, the C-131A, was derived from the 240 model, and was delivered to the USAF in 1954. A trainer model called the T-29 was also based on the Convair 240 to instruct navigators and radio operators. The T-29 was eventually replaced by the T-43. A planned bomber training version of the T-29 (designated T-32) was never built. The 340 model was used for most C-131Ds.
The U.S. Navy used the Samaritan as the R4Y. Nearly all of the C-131s left the active inventory in the late 1970s, but Air National Guard units operated a few into the mid-1980s. The C-131 was eventually replaced by the C-9 Nightingale.
A Samaritan was the first aircraft used as a flying gunship testbed in mid-1963, in a program known as Project Tailchaser. A C-131B (#53-7820) was given a gunsight for the side window, but instead of guns it had cameras in the cargo area. Eventually the C-131 was ferried to Eglin AFB in Florida and a General Electric SUU-11A/A 7.62mm Gatling-style Minigun was installed. Live ammunition was used and both over-water and over-land tests were successful.
[edit] Accidents and incidents
Three members of the southern rock band Lynyrd Skynyrd were killed when a Convair 240 they were aboard crashed near a forest in McComb, Mississippi on October 20 1977. The probable cause of the crash was fuel exhaustion and total loss of power from both engines. The pilot, co-pilot and the band's assistant road manager were killed also. Some 20 other passengers survived.
