N511AB

The airframe bearing registration and tail number N511AB is a 1981-built Cessna 550 Citation II, serial number 550-0299, manufactured by Cessna (Textron Aviation). The airframe is owned by SL JET LLC, an LLC based in Franklin, NC, US; it is registered in the United States and recorded under that single named corporate owner. The listed market valuation for this specific airframe is $900,000, reflecting its age, configuration, and market position among early-1980s light business jets. No additional historical operators or transfers beyond the current corporate ownership are published in the provided data.

The cabin of this airframe is configured for 8 occupants, aligning with the Citation II’s typical executive layout for small-group business travel. With a cruise speed of 369 kts and a maximum range of 1,900 nm, typical mission profiles for N511AB include medium-range point-to-point corporate flights, regional shuttle runs, and transcontinental legs within the continental United States when payload and fuel reserves permit. Based at the owner’s location in Franklin, NC, the aircraft is operated from a corporate base context under the ownership of SL JET LLC; maintenance considerations for this airframe follow standard practices for older-model Citations and the Pratt & Whitney Canada JT15D-4 turbofans. No specific interior refurbishments, avionics packages, or unique amenities were provided in the supplied data.

The Cessna 550 Citation II occupies the light, twin-engine business-jet niche, offering higher cruise and payload capability than earlier Citation variants while remaining positioned below midsize jets in cabin volume and range. Competing types during the same era included other light jets and early small-cabin offerings where buyers balance acquisition cost against operating economics. For a 1981 serial like 550-0299, maintenance status, engine cycles on the JT15D-4 powerplants, and structural inspection history are primary resale and operating-value determinants; the stated $900,000 valuation reflects those typical market and maintenance considerations.
