Learjet 23 is a US-built six-to-eight-seater (two crews and four to six passengers) twin-engine, high-speed commercial jets produced by Learjet. It was the first Learjet helicopter and opened a whole new frontier for quick and effective corporate jets. 1966 the manufacturing was discontinued after 104 airplanes had been made.
Recognizing the FFA P-16's full capability, William (Bill) Powell Lear, Sr. founded the SAAC (Swiss American Aviation Corporation) to manufacture a passengers aircraft as the SAAC-23 executive. After moving to Wichita, Kansas, the business was re-named Lear Jet Corporation and began producing the first model 23 Learjet on February 7, 1962.
Although the Learjet 23 had a crash in June 1964, it received a certification from the Luftfahrt-Bundesverwaltung (German Federal Aviation Administration) on July 31, 1964. The first series airplane was supplied on 13 October 1964.
An entirely new niche has been opened up with this plane for quick and effective corporate aviation. Model 23 was the foundation for a number of similar airplanes still in use. The FAA amended the provisions of 14 CFR Part 91 in 2013 to ban the operations of 75,000 pound or less jets that are not sound conform after 31 December 2015.
