N501SP

The airframe bearing tail number N501SP is a Cessna 501 Citation I/SP built in 1977 with serial number 501-0039. This specific airframe is recorded as owned by N501SP LLC, an entity based in Kalispell, MT, US; the current registration is held in the United States and ownership is shown under that LLC. The aircraft is a fixed-wing multi-engine business jet type with a compact executive cabin and carries an indicated market value of $500,000. Registry and valuation figures reflect an airframe nearing five decades of service and suggest typical aging and market considerations for late-1970s light jets.

The subject airplane features a single-pilot certified layout and a typical compact executive cabin arranged for 1+6/7 seating, providing utility for short to medium corporate missions or owner-flown operations. With a cruise speed of 352 kts and a range of 1,328 nm, the platform is commonly employed on regional point-to-point routes where runway performance and speed are prioritized over long-endurance capability. The airframe’s certified single-pilot capability reduces crew cost and complexity for private operators, while the compact cabin limits passenger capacity to business-appropriate loads. Maintenance considerations for this individual jet reflect its age and configuration, and the recorded ownership by N501SP LLC in Kalispell, MT, US places operational basing and regulatory oversight within the U.S. civil registry.

The Cessna 501 Citation I/SP occupies the light-cabin, short-to-medium-range sector of business aviation, offering higher cruise speed and altitude capability—up to 41,000 ft—than typical piston or turboprop alternatives. Competing models in its era and secondary market include other light business jets configured for single-pilot use; buyer and charter demand today tends toward more modern avionics and engines, affecting resale and maintenance economics. The modest valuation of $500,000 for this airframe indicates typical depreciation for a 1977 model and underscores the importance of inspection history and component life-limits in assessing continued operational viability.
