N777AX

This article covers airframe N777AX, a build-year 1988 Cessna S550 Citation S/II bearing serial number S550-0149. The aircraft was manufactured by Cessna (Textron Aviation Inc.) and is owned by HTJ AVIATION INC, a corporate owner based in Fort Lauderdale, FL, US. Registry and listing records identify aftermarket avionics additions and valuation notes; the airframe is publicly listed with an estimated market value of $1,100,000. Notable registry annotation includes its corporate ownership and home-base association with Fort Lauderdale, FL.

The cabin of N777AX is configured in an executive eight-place layout with a forward two-place divan, a mid‑cabin four‑place club, and two forward‑facing seats. Onboard furnishings include a refreshment center and an entertainment system to support executive transport missions. Avionics fit for this airframe is a mixed Collins suite augmented with a Collins TDR‑90 transponder, Honeywell Primus 300SL weather radar, Avidyne EX‑500 multifunction display, and a Garmin datalink (GDL‑69); listing records further report aftermarket Lynx/NGT devices installed. Typical operations for this airframe would align with short- to mid‑range corporate and charter missions out of its Fort Lauderdale base given its cruise speed and range. Maintenance considerations noted in public listings emphasize integration of mixed OEM and aftermarket avionics equipment.

The airframe belongs to the S550 Citation S/II family, a light business jet line positioned for efficient short- to medium-range executive transport with transcontinental capability in some mission profiles. Competitors in its performance niche historically include other light-cabin turbofan twins that offer similar cruise speeds and range. Buyer and charter demand for late‑1980s S/II airframes is influenced by avionics upgrades, engine shop status, and cabin refurbishment; resale and maintenance considerations for N777AX are therefore tied to its mixed Collins avionics pedigree and reported aftermarket enhancements.
