N405DC

This entry covers airframe N405DC, a 2008-built Learjet 60 / 60XR with serial number 60-363, manufactured by Learjet Inc. / Bombardier Aerospace. The aircraft is currently owned by COS AIR LLC of Boca Raton, FL, US, and is U.S.-registered; detailed historical registry transfers are Not published. The frame is listed in broker material in a charter-ready executive configuration and carries an estimated market value of $13,650,000; condition highlights beyond advertised configuration were not provided.

The cabin is offered in an advertised charter configuration described as a 6–8 passenger executive layout, with a broker listing showing accommodation for up to 7 passengers while the FAA certificated seating is 11. Typical operations for this airframe are consistent with light business-jet charter missions within the transcontinental and near-oceanic range enabled by a 2,451 nm ferry capability and a high-speed cruise of 453 kts. Based in Boca Raton, FL, US under ownership of COS AIR LLC, the airframe is operated as a fixed-wing multi-engine corporate/charter asset; specific avionics fit and maintenance records for this serial were not provided. Given the twin PW305A installation, routine engine and airframe maintenance considerations follow the model’s established inspection cycles and operator maintenance programs.

The Learjet 60 / 60XR family occupies a mid-size, high-speed light-business jet niche, offering high cruise speeds and a 51,000 ft service ceiling suitable for efficient point-to-point charter operations. Competing models typically include other light-to-midsize business jets that trade cabin volume, range, and operating cost; the 60/60XR’s appeal centers on speed and altitude performance. For buyers and charter operators, resale and maintenance considerations hinge on serial-specific records, engine cycles on the PW305A pair, and interior configuration differences between FAA-certificated seating and broker-advertised executive layouts.
