N637AT

This entry covers airframe N637AT, a build-year 1979 Cessna 550 Citation II with serial number 550-0371. The aircraft is listed in the U.S. registry and is owned by N637AT LLC, an entity registered as an LLC based in Punta Gorda, FL, US; this ownership is the most recent recorded operator-level detail. The airframe has been identified in operator materials as a Citation II configured for medevac/air-ambulance duties, and its assessed market value is $800,000. Maintenance and operational use have reflected its age and specialized role rather than typical corporate shuttle service.

The cabin is configured as an 8-passenger executive layout, though the operator lists the aircraft specifically as a Citation II used for medevac/air-ambulance duties, indicating interior arrangements and equipment may be mission-modified. Typical mission profiles for this particular airframe would include short- to mid-range medical evacuation flights and urgent passenger transport within its 1,998 nm range and at cruise speeds around 403 kts. Based in Punta Gorda, Florida, the operator-level location supports regional operations across the southeastern United States and Caribbean routes within the aircraft’s performance envelope. Maintenance considerations for this airframe reflect its 1979 manufacture date and the Pratt & Whitney Canada JT15D-4 turbofan powerplants, with lifecycle and parts availability influencing dispatch reliability and operating economics.

The airframe belongs to the Cessna 550 Citation II family, a light corporate twinjet niche known for its combination of short-field capability and transcontinental short-haul performance. Competing models in its era and market include other late-1970s to 1980s light midsize business jets offering similar cruise speeds and ceilings, though buyer demand has shifted toward newer airframes with modern avionics. Resale and maintenance considerations for N637AT center on its age, specialized medevac use, and the continued supportability of JT15D-series engines, factors which contribute to its assessed value of $800,000.
