Description
N70CG is a well-equipped 1981 Citation 501SP, privately operated under Part 91, professionally flown, always hangared and meticulously maintained. Importantly, the 501SP is factory type-certificated for single-pilot operation when equipped and operated in accordance with the AFM, distinguishing it from CE-500-series aircraft that relied on recently rescinded FAA single-pilot exemptions. Highlights include a new 2026 interior with modern neutral colors and executive club seating, excellent Greenpoint Aerospace exterior, thrust reversers, RVSM, 9,500 lb Zero Fuel Weight upgrade, dual WAAS navigation, ADS-B, traffic, EGPWS, satellite weather and Freon air conditioning. The aircraft has received attentive recent maintenance, including Phase 5 in December 2025, Phases 1–4 in July 2026, significant landing gear maintenance, new deice boots, new tires and numerous additional maintenance items. Known squawks have been addressed, and the aircraft presents exceptionally clean and well cared for for its year, with no known outstanding squawks at the time of listing. With approximately 6,922 hours total time and 5,700 landings, N70CG presents as a well-maintained and highly equipped Citation 501SP.

See prices & suppliers ›No autopilot is listed — a GFC 600 or S-TEC 3100 digital autopilot is a major capability and value add, subject to STC approval for this model.
Shop options ›Suggestions are based on the panel described in this listing; verify STC approval for this make/model before any installation.
