N111SG

The airframe registered as N111SG is a 1980-built Cessna 550 Citation II with serial number 550-0196, manufactured by Cessna (Textron Aviation Inc.). The aircraft is registered in the US and carries a listed market valuation of $675,000 reflecting its vintage and outfitting. Ownership timeline and operator/home base not published; notable registry actions not published. The airframe’s age, configuration and avionics fit are primary valuation and condition indicators for prospective operators or buyers.

This specific Citation II is fitted in an executive seven-passenger layout featuring a center-club seating arrangement with a forward refreshment center and an aft belted flushing lavatory, configured for executive transport and short- to mid-range missions. The avionics fit for N111SG includes a Collins Pro Line avionics suite augmented by a Garmin GTN-650 navigator, Honeywell IHAS-8000 TAWS/TCAS, Honeywell RDR-2000 weather radar and a Garmin GTX-330ES transponder providing ADS-B Out capability, supporting contemporary airspace compliance and operational situational awareness. Typical mission profiles for this configuration would be owner-flown or light charter work over the aircraft’s approximately 2,000 nm range at cruise speeds near 403 knots; operator/base details not published. Maintenance considerations for continued operations center on older airframe inspections, engine program management for the JT15D-4s and avionics support for mixed Collins/Garmin/Honeywell systems.

The Cessna 550 Citation II occupies a light twin-engine business jet niche characterized by relatively high cruise speed and a 43,000 ft service ceiling, making it suited to point-to-point regional and transcontinental hops within its range. Competing models historically include other late-1970s and 1980s light business jets offering similar capacity and mission flexibility; buyer demand is often focused on acquisition price, avionics upgrades and the cost of maintaining older Pratt & Whitney JT15D engines. Resale and maintenance considerations for this airframe emphasize inspection status, avionics modernity (the presence of ADS-B Out and integrated TCAS/TAWS is positive) and total-time/overhaul status of engines and airframe systems.
