N504SF

This airframe, registered as N504SF, is a Cessna 501 Citation I/SP with serial number 501-0643. It is registered to SHB AVIATION LLC of Indianapolis, IN, US, the corporate owner recorded on U.S. registry documents. The airframe is a fixed-wing, multi-engine business jet in single-pilot capable configuration and is operated from the owner’s Indianapolis base for corporate and executive transport. Publicly available registry entries identify the U.S. registration and corporate ownership; further discrete valuation or condition reports are not published for this specific airframe.

The cabin of this Citation I/SP is configured in a single-pilot capable executive layout, model-typical for 1 + 5–7 passengers and built to serve small corporate parties or owner-operators. Typical missions for this airframe, given its 1,328 nm range and 357 kts cruise, include regional business travel and point-to-point transport across the continental U.S., with flight profiles up to its 41,000 ft ceiling to optimize fuel efficiency and traffic separation. Specific avionics suite and interior finish for N504SF are not published; maintenance considerations center on the twin Williams FJ44-2A turbofan engines, which are noted for modern small-jet efficiency but require operator attention to life-limited components and timely accessory overhauls.

The Cessna 501 Citation I/SP occupies the light-cabin, entry-level business-jet niche within Textron Aviation’s Citation family, emphasizing single-pilot flexibility, modest operating costs, and useful short-to-medium range capability. With seating for up to eight and transcontinental-but-not-intercontinental range, demand typically comes from owner-operators, small corporations, and charter operators seeking cost-effective, fast regional travel. Market and resale considerations for this model commonly hinge on engine program status, avionics upgrades, and overall interior condition; the presence of Williams FJ44-2A powerplants and single-pilot certification are relevant factors in valuation and continued utility.
