The Convair CV-240 is an American airliner produced by Convair from 1947 to 1954, initially as a possible replacement of the ubiquitous Douglas DC-3. Featuring a more modern design with cabin pressurization, the 240 series was able to make some inroads as a commercial airliner and also had a long development cycle which resulted in various civil and military variants. Although reduced in numbers through attrition, the "Convairliners" in various forms continue to fly into the 21st century.

 

The design began its life in a requirement by American Airlines for an airliner to replace its Douglas DC-3s. Convair's original design, the unpressurised Model 110, was a twin-engine, low-wing monoplane of all-metal construction, with 30 seats. It was powered by Pratt & Whitney R-2800 Double Wasp radial engines and had a tricycle landing gear and a ventral airstair for passenger boarding. The prototype Model 110, registration NX90653, first flew on July 8, 1946.[2] By this time, American had changed its requirements to require pressurization and deemed the design too small. The first prototype was used by Convair for development work for the 240 series before being broken up in 1947.

After aborted negotiations with TWA and Eastern for "Super 240" orders, the production of the 240 series was temporarily halted. In response to a United inquiry, Convair redesigned the Super 240, calling it the CV-340. United ordered 55, and more US orders came from Braniff, Continental, Delta, Northeast and National. Other orders came from abroad, and the CV-340 proved popular in South America. The CV-340 earned an enviable reputation for reliability and profitability, and was developed into the CV-440 Metropolitan, the final piston-engined variant of the "Convairliners.

Conversion from Convair CV-340 (Allison Prop-Jet Convair 340) or CV-440 aircraft with two Allison 501 D13D/H turboprop engines with four-blade propellers, in place of piston engines with three-blade propellers, an enlarged vertical fin and modified horizontal stabilizers. The conversions were performed by Pacific Airmotive on behalf of the Allison Engine Company.[13] Cost of the conversions was around £175,000 per aircraft and took 60 days.
