N321SM

The airframe bearing registration N321SM is a 2009-built Cessna 525B Citation CJ3, constructor serial number 525B0320. The aircraft was manufactured by Cessna Aircraft Company (Textron Aviation) and is currently owned by Lucky Stars LLC, a limited liability company based in Missoula, MT, US. The airplane is registered in the United States and has been operated from its Missoula home base under the ownership of Lucky Stars LLC. No major public registry actions beyond standard U.S. registration are published for this specific airframe.

The cabin on this CJ3 is configured in a typical 6–8 place executive layout featuring forward club seating and belted divan options; this particular airframe may be fitted with an enclosed aft lavatory depending on customer fit. Avionics for the production CJ3 are commonly the Collins Pro Line 21 suite, which is the typical fitment described for this airframe generation; later Citation CJ3 Gen3 variants use the Garmin G3000 but that does not apply to the original 2009 CJ3 production baseline. Typical missions for N321SM would include short- to mid-range executive transport and charter work within its 2,040 nm range and 416 kt cruise capability, often operating from regional airports in and out of Missoula, MT. Maintenance considerations for this airframe follow Williams FJ44-3A engine programs and Collins Pro Line avionics support common to the model.

The Cessna 525B Citation CJ3 occupies the light business jet niche, offering a balance of short-field capability, transregional range and efficient twin Williams FJ44 engines. It competes with other light jets in the same class, where buyers and charter operators value low operating costs, eight-place cabin flexibility and a high-altitude ceiling of 45,000 ft for fuel-efficient cruise. Resale and maintenance considerations for a 2009 CJ3 such as N321SM typically center on engine program status, avionics configuration (Pro Line 21 versus later G3000 retrofits) and overall interior condition given the common executive seating arrangements.
