N797SE

The airframe bearing registration N797SE is a 1980-built Cessna 501 Citation I/SP, serial number 501-0151, manufactured by Cessna (Textron Aviation). It is recorded in the US registry and is currently registered to Douglas W, an individual based in Seabrook, TX, US, reflecting a single-owner/individual-operator status in public records. The airframe’s configuration, production vintage and serial identify it as an early-production Citation I/SP example; registry entries note its US registration and ownership rather than corporate or fractional operation. Condition and valuation highlights are limited to registry details and typical configuration for early Citation I/SP installations.

The cabin for this airframe follows the executive arrangement typical of early Citation I/ISP examples, configured for 5–8 executive seats in a compact business-jet layout suited to owner-operator use. Avionics installations for early Citation I/ISP examples are typically the Collins Pro Line I, which defines the flightdeck equipment and influences upgrade and maintenance priorities for this specific aircraft. With a cruise of 323 kts and a range of 1,328 nm, the aircraft is operated for short- to mid-range business travel out of its Seabrook, TX home base, supporting point-to-point missions within a domestic/regional footprint. Maintenance considerations for this airframe reflect its production era and the installed JT15D-1 powerplants, with systems and avionics typical of 1980-era Citation I/SPs.

As a member of the early Citation I/SP family, the airframe represents the light, fixed-wing multi-engine business-jet niche, offering moderate range and high-altitude capability with a 41,000 ft ceiling. The performance profile—323 kts cruise and 1,328 nm range—positions the platform for owner-operated executive missions and short charter roles. Market and resale considerations for this vintage center on airframe hours, engine status, and avionics modernization (notably units with original Collins Pro Line I installations), all factors that influence buyer and charter demand for a 1980 Citation I/SP example.
