N420PC

This airframe, registered as N420PC, is a 1981-built Cessna 501 Citation I/SP with manufacturer serial number 501-0237. The airframe is listed in the US registry and is currently owned by MB Citation LLC, an LLC based in Neenah, WI, US, reflecting private LLC ownership rather than individual operator custody. The airframe retains much of its original build vintage and Collins-era avionics heritage, and is valued in current listings at $791,000, a figure that reflects age, system configuration and market position for early Citation I/SP examples.

The cabin of this specific airframe is configured in an executive club layout and is described as typically accommodating 5–6 passengers with an aft lavatory, although final fit is operator-specific. Avionics fit on this airframe is consistent with original I/SP installations, commonly featuring Sperry SPZ-500 equipment and Collins-era avionics components; individual panel fit may vary by airframe and any subsequent upgrades. Typical missions for the Citation I/SP airframe include short-to-medium range business trips and owner-operator transport within the aircraft’s 1,328 nm range and cruise speed near 357 kts, operating from the owner’s base in Neenah, WI, US for regional hops. Maintenance considerations for this example will reflect its early-1980s airframe age, twin JT15D-1A turbine heritage, and any operator-specific avionics modernization or airframe refurbishments.

The Cessna 501 Citation I/SP occupies the light business jet niche as an early Citation family design, offering single-pilot capability, modest cabin capacity and efficient short-to-medium range performance. In the contemporary used market it competes with other light jets from the same era, and demand is typically driven by cost-conscious owner-operators or charter companies seeking economical short-range capability. Resale and maintenance considerations for a 1981 airframe like 501-0237 hinge on engine times and overhauls of the Pratt & Whitney Canada JT15D-1A engines, the condition and upgrades of original Collins-era avionics and Sperry systems, and overall corrosion/airframe inspections typical for aircraft of this vintage.
