N505JH

The airframe bearing tail number N505JH is a 1979-built Cessna 501 Citation I/SP, serial number 501-0126, listed on U.S. registry and currently owned by QWIRK JET LLC of Brooklyn, New York. This specific airframe’s documented operator/home base is Brooklyn, NY, US, and contemporary listings note an executive interior configuration in its history. Public equipment and listing summaries for this airframe reference avionics and weather radar fits typical of upgraded late-model Citation I/SPs, while valuation or condition records for this hull are not published in the supplied data.

The cabin for this airframe is described in executive-configured terms, with typical layouts cited as a 5–6 passenger executive arrangement and historic listings specifically referencing a 6-place executive layout; the aircraft is therefore outfitted for short-to-medium-range executive transport missions consistent with light business jets. Avionics and mission equipment reported in as-equipped listings include the Garmin GTN 750 and Garmin GNS 530 navigation/comm units, a GTX 330ES transponder, Honeywell RDR-2000 weather radar, and a Sperry SPZ autopilot/flight director, supporting single-pilot or two-pilot IFR operations depending on operator configuration. With its listed range and cruise speed, this airframe would typically be used for regional point-to-point charters, owner-operator business travel, and short international hops from its Brooklyn base, and maintenance considerations follow standard Pratt & Whitney JT15D-series inspection and overhaul cycles.

The Cessna 501 Citation I/SP occupies the light business jet niche as a small, twin-engine executive transport from the late 1970s with modest speed, range, and operating costs relative to larger Citations. Competing models in the era and resale market include other light jets powered by early-generation turbofans; buyer and charter demand for well-equipped, refurbished airframes often hinges on avionics upgrades (such as the Garmin GTN 750/GNS 530 fit noted) and cabin refurbishment. For this hull, maintenance and resale considerations are dominated by the airframe’s age, serial-specific history, and the cost and availability of JT15D-line engine overhauls and legacy-system updates.
