    Originally designed in Switzerland as the SAAC-23, the Learjet was put into production in 1962 by it's designer, William P Lear, then later sold to the Gates Rubber Co. The Learjet line was subsequently sold to Bombardier of Canada in June 1990 and the name changed to Learjet Inc.  The aircraft are built at Mid-Continent Airport in Wichita, Kansas and fitted out there and at the Bombardier facility in Tucson, Arizona.

    Spiritwing Conversion

    http://www.spirit-wing.com
    .
    Spiritwing Aviation of Oklahoma is offering a re-engining conversion for all 20 series Learjets bar the 23.  The original General Electric CJ610's are replaced with Williams Rolls FJ44-2C giving a fuel consumption reduction of 60% and a range increase to 3000km from the original 2000km. Cost per aircraft is 1.7 million dollars and supplemental type certification is hoped for in late 2003.  Conversion takes about 90 days and the first flight using a Lear 25D was made on 9th January 2003.  The engines are mounted slightly farther out, up and back than the original and changes are also made to the nacelles, pylons, fuel systems and electronics.
