N501MF

The airframe described is N501MF, a Cessna 501 Citation I/SP (Citation ISP) built in 1982 with serial number 501-0244. It is registered in the US and is owned by GREYSHORE AVIATION LLC (a corporation based in Mystic, CT, US). The airframe appears in transactional material with an equipment list referenced as a sale listing; the same documentation lists an estimated market value of $475,000 and details its fitted avionics and cabin configuration. Current ownership by GREYSHORE AVIATION LLC and the sale-listing equipment sheet are the primary registry/transaction notes available for this airframe.

The cabin of N501MF is arranged with a forward lavatory, a forward single seat, a center 4-place club, yielding an overall seven–belted passenger configuration. Avionics equipment fitted to this airframe, as listed on the sale listing equipment sheet, includes a Garmin GNS-530W, Garmin GTX-345 transponder, Garmin GMA-340 audio panel, Avidyne EX‑500 MFD, Bendix color radar, SPZ‑500 autopilot and KGP‑560 EGPWS. Typical missions for a Citation I/SP of this configuration would center on short-to-medium corporate hops or owner-flown business travel consistent with its cruise speed and range; the listed base of the owning corporation in Mystic, CT suggests northeastern U.S. operations. Maintenance considerations for this specific airframe would reflect its early-1980s manufacture date and twin JT15D engines, with avionics modernizations noted on the equipment sheet relevant to continuing airworthiness and resale readiness.

The Cessna 501 Citation I/SP occupies the light business jet niche that emphasizes modest operating costs, straightforward systems, and owner-pilot capability compared with larger airframes. Competitors historically include other light jets of the early 1980s era; demand on the used market typically depends on avionics updates, engine time, and overall refurbishment. For N501MF, the combination of updated avionics listed and a low-market valuation of $475,000 informs resale and charter prospects but also signals potential for required maintenance, inspections, or interior refresh given the airframe’s age.
