N585BG

The airframe N585BG is a 1980-built Cessna 501 Citation I/SP, serial number 501-0185, registered in the United States. The airframe is owned by GUARDIAN AERO LLC (a corporation based in Wilmington, DE, US) and appears in civil registry under corporate ownership with a noted valuation of $599,000. The type is a fixed-wing multi-engine executive light jet and the current listing-level description emphasizes a six-passenger executive interior and contemporary avionics upgrades. Corporate acquisition and current operation from Wilmington, DE are the principal recorded ownership events for this specific airframe.

The cabin of N585BG is configured as an executive six-passenger layout with four club chairs and an aft-facing seat, reflecting a typical corporate transport arrangement for short- to medium-range missions. Avionics fit on this airframe includes a Garmin GTN 750/650 suite, Sandel SA4550/SN4500 attitude and navigation displays, Garmin 345 transponder with ADS‑B Out, Sperry SPZ-500 autopilot, Bendix RS-811A weather radar, Sandel TAWS-B, and a Collins communications/navigation suite as listed. Typical mission profiles for this airframe would emphasize point-to-point corporate travel within its 1,326 nm range at cruise speeds near 352 knots, operating to FL410 in favorable conditions. Maintenance considerations reflect the twin JT15D turbine installations and legacy airframe systems common to early 1980s Citation I/SP examples; avionics modernization noted on listings can improve operational utility and airspace compliance.

The Cessna 501 Citation I/SP occupies the light-cabin executive jet niche, offering efficient short-field performance and relatively low crew/operating complexity compared with larger Citation variants. Competing models in its era and residual market include early Learjet and Dassault Falcon 10 derivatives that target similar mission profiles. Buyer and charter demand for this class centers on owner-operators and small-corporate fleets seeking economical transcontinental capability; resale value and marketability of this specific airframe will be influenced by avionics upgrades, engine overhaul status, and completed maintenance records. Maintenance and resale considerations are also affected by the JT15D engine commonality and the airframe’s 1980 build date, making documented upgrades and inspections key factors for prospective purchasers.
