N477LC

This article describes airframe N477LC, a 1988-built Cessna S550 Citation S/II with serial number S550-0153. The airframe is registered in the United States and is recorded as owned by L-3 IS LLC, an LLC based in Kalispell, MT, US, a fact occasionally referenced in public registry entries. The aircraft’s registration history is straightforward, with no public record of multiple operators or major registry transfers beyond its current LLC ownership. No public valuation or detailed condition report is published for this specific airframe.

The airframe is configured with a typical eight-place executive cabin layout, accommodating 7–8 pax in executive seating for corporate or private missions. Based from Kalispell, MT, the aircraft’s performance—particularly its near-2,000 nautical mile range and 403 kt cruise—supports regional to transcontinental sectors in North America, often used for point-to-point executive transport, charter hops, and business travel linking secondary cities. While specific avionics fit and interior finish for this serial are not published, the S550 platform commonly features a compact executive cabin optimized for short- to medium-duration flights; maintenance considerations center on age-related airframe and engine life-cycle items typical for 1988-built jets and JT15D-series powerplants.

The Cessna S550 Citation S/II occupies the light-citation category, marketed for owners seeking efficient short-to-medium-range executive transport with low runway performance and classroom-style operating economics. With twin Pratt & Whitney Canada JT15D-4 engines providing moderate thrust, it competes historically with other light jets of the era in charter and owner-operator markets. Buyers and charter operators evaluate these airframes on availability of avionics upgrades, maintenance history, and remaining structural and engine life—factors especially pertinent for a 1988 serial such as S550-0153 when considering resale and continued operational use.
