N550GZ

This article covers a single airframe, tail number N550GZ, a 1979-built Cessna 550 Citation II with serial number 5500092. The airframe is registered in the United States and is owned by FLYBYNIGHT LLC, an Imperial, California–based limited liability company. The airframe’s identity and basic provenance are established by its serial and registration; no other operators or registry actions are published in the supplied data. Condition and valuation specifics are not published beyond the aircraft’s model-year and ownership information.

The cabin for this specific airframe is described in manufacturer and common retrofit practice as a typical mid-cabin executive club layout seating 7–8 passengers with a belted aft lavatory common on retrofit examples; in this instance the stated seating count is 8. As a light business jet operated from an Imperial, California–based LLC, its typical missions would align with short- to medium-range executive transport within the stated range of 1,998 nm and cruise speed of 369 kts. Avionics fit, maintenance logs, and configuration-specific amenities are not published in the supplied data; routine maintenance considerations for this airframe type would center on its twin Pratt & Whitney Canada JT15D-4 turbofans and age-related systems inspection given its 1979 build year. The aircraft’s U.S. registration and LLC ownership imply private operation rather than scheduled commercial service.

The airframe belongs to the Cessna 550 Citation II family, a fixed-wing multi-engine light business jet designed for short- to mid-range executive transport with a cruise speed and ceiling supportive of efficient regional routing. In the market context, the Citation II competes with contemporaneous light jets offering similar seating and range; buyer and charter demand historically favors durable airframes with updated avionics and well-documented maintenance. Resale and maintenance considerations for this serial and vintage center on engine time, structural inspections, and any modernization or retrofit work — factors particularly pertinent for a 1979-built airframe operated by a private LLC.
