N501BB

This entry covers the specific airframe bearing tail number N501BB, a Cessna 501 Citation I/SP manufactured by Cessna (Textron Aviation) in 1978 with serial number 501-0087. The airframe is registered in the United States and is recorded as owned by WNO TRUST SERVICES LLC TRUSTEE, a trust based in Wilmington, DE, US; this ownership is the principal recent registry action on file. The airframe has an estimated market value of $600,000, reflecting its age and configuration as an executive light business jet. Maintenance and valuation notes indicate a mature airframe typical of late-1970s Citation I/SPs operated in corporate or trust ownership.

The aircraft is configured as an executive cabin with an operator-configured layout reported as a 6-place executive arrangement in some sources; operator records and secondary reports list a 6-passenger executive cabin layout. Typical mission profiles for this airframe use its light-jet performance for short to mid-range business hops within a single-ship range of approximately 1,328 nm at cruise speeds near 357 kts, capable of operating into smaller business airports while offering a trans-regional capability. Specific avionics fit and optional cabin amenities are not published for this serial; routine maintenance considerations align with older JT15D-powered Citation I/SP examples, including age-related component overhauls and compliance with legacy airworthiness directives.

The Cessna 501 Citation I/SP sits in the light twin-jet niche as an early Citation family entry, offering modest speed and high-altitude capability to 41,000 ft with simple, economical systems by later-generation standards. Competing types historically include other light business jets of the late 1970s and early 1980s; buyer and charter demand for this vintage model tends to focus on owner-operators or trusts seeking low-hour examples for corporate transport. Resale and maintenance considerations for this airframe emphasize engine hot-section life, avionics upgrades to meet modern airspace requirements, and the market reality reflected by its assessed value of $600,000.
