N5RL

The airframe bearing tail number N5RL is a Cessna 501 Citation I/SP built in 1981 with manufacturer's serial 501-0228. The airframe is currently registered in the United States to UNDER THE RADAR LLC, an LLC based in Dover, DE, US, and is operated from that location as its apparent home base. No public record of prior owners or notable registry actions beyond the current registration is provided in the supplied data. Condition and valuation details are not published for this specific airframe in the data set.

The subject aircraft in its eight-seat configuration is consistent with light business jet missions focused on short- to mid-range point-to-point transportation and owner-operator use. Cabin layout for the Cessna 501 Citation I/SP typically accommodates a single-club forward seating with a four-place executive arrangement aft and belted lavatory or storage, although specific interior fit and refurbishment history for N5RL are not published. Avionics fit for this airframe is not published in the provided data; therefore, typical mission profiles would include regional hops within the aircraft’s 1,328 nm range and higher-altitude cruise to the 41,000 ft service ceiling, leveraging the twin JT15D-1A engines for higher-speed climbs and cruise at 357 kts. Maintenance considerations for an airframe built in 1981 would center on lifecycle component inspections, engine hot-section history, and avionics upgrades to meet contemporary airspace requirements.

The Cessna 501 Citation I/SP occupies the light-cabin business jet niche of the early 1980s, offering economical twin-engine performance for owner-flown and small charter operations. Its performance—cruise near 357 kts, ceiling to 41,000 ft, and a range of 1,328 nm—positions it against contemporaries such as early Learjet and small Gulfstream turbofan types, appealing to buyers seeking simplicity and lower acquisition cost versus newer entrants. Market demand is generally driven by availability of well-maintained examples, avionics modernization, and engine time remaining; resale and maintenance considerations for N5RL would reflect its 1981 airframe age and the status of component life-limited parts and JT15D engine cycles.
