N91HG

The airframe bearing tail number N91HG is a 1981-built example of the Cessna 501 Citation I/SP, serial number 501-0199, manufactured by the Cessna Aircraft Company (Textron Aviation). The airframe is registered in the US and is owned by the corporation MONSON CREEK RANCH INC, listed in Mobile, Alabama, United States; this corporate ownership represents the primary recorded ownership timeline for this specific airframe. There are no additional public registry actions listed beyond the current corporate registration. Condition and valuation entries for the airframe place it at an assessed market value of $650,000, a figure that reflects its vintage 1981 build and typical maintenance considerations for airframes of this age and type.

This individual Citation I/SP is outfitted in the single-pilot I/SP configuration with a typical executive cabin layout accommodating 5–8 passengers, oriented toward short- to mid-range corporate missions and owner/operator use. Based on the registered owner location in Mobile, Alabama, typical operations for this airframe would include regional executive transport, business trips within the continental United States, and ferry legs consistent with a 1,328 nm range and a high-speed cruise capability of 322 knots. Avionics fit is not published in the provided data; maintenance considerations center on legacy systems and airframe aging typical of early-1980s Citation Is, with operator-level upkeep and component life limits influencing dispatch reliability and operational costs.

The Cessna 501 Citation I/SP occupies a small-cabin, light business jet niche characterized by efficient short-to-medium range missions and single-pilot certification in the I/SP variant. With twin Pratt & Whitney Canada JT15D-1 engines producing 2,200 lbf each, the type offers respectable climb and cruise performance to a 41,000 ft ceiling for its class. Competing types historically include other light fanjets of the late 1970s and early 1980s; resale and maintenance considerations for this particular airframe reflect its 1981 vintage, corporate ownership structure, and the assessed market value of $650,000.
