N80SL

The airframe bearing registration N80SL is a 1979-built Cessna 501 Citation I/SP, serial number 501-0294, manufactured by Cessna (Textron Aviation). As of the latest available registry data this airframe is owned by Technical Systems Management Corp, a corporation based in Cudjoe Key, FL, US, and is operated from that location. The aircraft is registered in the US; public records do not document additional prior ownership or notable registry actions for this specific serial. Condition and valuation highlights are not publicly published for this particular airframe.

The airframe typically reflects a standard executive interior for the Citation I/SP line, described generically as a 5–8 place executive layout, although the exact interior configuration for this specific airframe is not publicly documented. Avionics fit for this serial is not published in the provided data; operators of this model commonly configure the flightdeck for short- to medium-range business missions. Based at Cudjoe Key, FL, the owner-operator profile suggests regional corporate transport, short cross-country hops and island-hopping missions consistent with the aircraft’s range and cruise capability. Maintenance considerations for this individual airframe follow the JT15D powerplant and airframe schedules customary to late-1970s Citation I-series jets, with routine inspections and systems updates driven by owner/operator needs and any supplemental inspection programs they elect to follow.

The Cessna 501 Citation I/SP occupies the light corporate jet niche, emphasizing short-field performance and efficient single-pilot capable operation relative to larger business jets. With twin JT15D-1A engines producing 2,200 lbf each, the model offers a cruise around 352 kts and a high-altitude capability to 41,000 ft, suiting point-to-point business travel and on-demand charter work. Competing models in this segment historically include other late-1970s light jets offering similar seating and range; buyer and charter demand tends to favor well-maintained airframes with documented upgrades. Resale and maintenance considerations for this serial would hinge on interior condition (not published), avionics modernization, and adherence to OEM and aftermarket inspection programs.
