N505CF

The airframe bearing registration N505CF is a 1979 Cessna 501 Citation I/SP, serial number 501-0130, manufactured by Cessna Aircraft Company (Textron Aviation). The aircraft is registered in the United States and is owned by W BROWN ENTERPRISES INC, a corporation based in Durant, Oklahoma. This write-up focuses on this specific airframe’s construction year, serial, and current corporate ownership; no other registry transfers or valuation entries are published for this tail. The airframe’s documented configuration and systems provide the primary condition and capability indicators for operational use and market comparison.

This Citation I/SP is outfitted in an eight-place executive cabin layout with a forward refreshment center, an aft four-place club, and a removable aft belted lavatory; the typical configuration noted is a six-passenger club plus pilots. Avionics fit on this airframe comprises Collins ProLine components, including Collins radios, Dual VHF-20, VIR-30, TDR-90 transponders, a KMD850 multifunction display, KGP560 EGPWS, and TCAS, supporting modern navigation, surveillance, and terrain awareness capabilities. Operating from its corporate base in Durant, Oklahoma, the aircraft’s combination of cruise speed and range make it suited to short- to mid-range executive transport and business missions where cabin flexibility (removable lav) and compact executive amenities are desired. Engine and avionics maintenance considerations follow the typical light business-jet profile implied by twin JT15D powerplants and ProLine avionics, with corporate ownership suggesting retention of a consistent maintenance schedule.

As a Cessna 501 Citation I/SP airframe, this aircraft occupies the light business jet performance niche characterized by cruise speeds in the mid-300-knot range, transcontinental-ish range capability near 1,328 nm, and service ceilings up to 41,000 ft. The eight-place executive cabin layout and established Pratt & Whitney Canada JT15D-1A propulsion provide owners and operators a balance of passenger capacity and operating economy for corporate missions. Maintenance and resale considerations for this specific serial and build year center on vintage-system upkeep, the help of upgraded avionics like Collins ProLine on this airframe, and the market appeal of an executive-configured, well-documented corporate-registered Citation I/SP.
