Learjet aircraft in the FAA registry
Learjet was a manufacturer of business jets for civilian and military use based in Wichita, Kansas, United States. Founded in the late 1950s by William Powell Lear as Swiss American Aviation Corporation, it became a subsidiary of Canadian Bombardier Aerospace in 1990. The Learjet line was once sufficiently popular that the name became synonymous with private jets.
Data from the FAA registry, current as of 2026-10-16, lists 198 aircraft under the manufacturer name "GATES LEARJET CORP." All 198 entries are classified as fixed-wing multi-engine aircraft. Of these, 196 registrations are valid. The fleet consists primarily of turbofan engines (189) and turbojet engines (9). Airworthiness classes include standard (178), restricted (6), and multiple (2).
The majority of these aircraft were built between 1976 and 1990. Half of the fleet was built in 1981 or earlier. The most registered model is the Learjet 35A, with 135 aircraft recorded. These were built from 1976 to 1989 and accommodate 10 seats. The Learjet 55 follows with 54 registrations, built between 1981 and 1986 with 13 seats. Smaller numbers include the Learjet 55C (6 aircraft) and Learjet 55B (3 aircraft), both with 13 seats.
Geographically, Delaware holds the most registrations with 37, followed by Michigan with 36 and Florida with 22. The Type Certificate Data Sheets (TCDS) for these top models are held under TCDS A10CE by Learjet Inc. This certificate covers the 35A, 55, 55C, and 55B. The FAA registry also lists aircraft under the name "LEARJET INC," which accounts for 846 aircraft.
The FAA registry also lists this company's aircraft as LEARJET INC.
