N20RM

The airframe bearing tail number N20RM is a 1977-built Cessna 501 Citation I/SP, serial number 501-0025, currently held in corporate title by SDI AVIAITON LLC of Rhinelander, WI, US. The aircraft is registered in the US and, in brokerage and valuation summaries, is listed at $600,000, reflecting its vintage airframe and systems status. Ownership is recorded to an LLC based in Rhinelander, which serves as the operator/home base for this airframe. Registry and valuation entries emphasize its age and attendant maintenance considerations consistent with a 1977 production Citation I/SP.

The subject airframe is configured for an eight-seat cabin, consistent with light business jet operations and short- to mid-range executive transport. Operated from Rhinelander, WI, US by SDI AVIAITON LLC, typical mission profiles for this airframe include regional point-to-point trips within the aircraft’s 1,328 nm range at cruise speeds near 357 kts, exploiting the 41,000 ft ceiling for efficient climb and fuel-burn regimes. As a 1977 Citation I/SP, the aircraft will commonly require continuing maintenance, avionics updates and component life-cycle management appropriate to its age; such considerations are reflected in its stated market value. Cabin layout is oriented toward executive seating rather than high-density transport, and operations tend to emphasize flexibility for charter or owner-flown business travel.

The Cessna 501 Citation I/SP occupies the light-cabin turbofan business jet niche, offering modest range and high-speed cruise relative to turboprop alternatives of its era. Powered by twin Pratt & Whitney Canada JT15D-1A engines delivering 2,200 lbf each, the type competes historically with contemporary light jets for owners seeking runway performance and single-pilot capability. In secondary markets, 1970s-model Citations trade at values reflecting airframe age, avionics fit, recent maintenance history and engine time; the $600,000 valuation for N20RM is indicative of these resale and upkeep factors. Buyers and charter operators considering this airframe must weigh vintage maintenance requirements and potential retrofit costs against the aircraft’s proven operational capabilities.
