N521TM

The airframe bearing tail number N521TM is a 1992-built Cessna 550 Citation II, serial number 550-0705, manufactured by Cessna (now Textron Aviation). This specific airframe is owned by IDAHO POWER COMPANY, a corporation based in Boise, ID, US, and is registered in the US registry. Registered in the United States and operated out of Boise, Idaho, the jet has the executive configuration and mission profile typical of corporate-operated Citation IIs. Publicly available registry actions and detailed valuation or condition assessments for this specific serial are not published here.

The airframe is fitted in an executive eight-passenger cabin layout typical for the Citation II lineage, configured for corporate transport and short to medium-haul missions. With a cruise speed of 403 kts and a maximum range of 1,998 nm, typical operations from the owner’s Boise base would include regional corporate flights, utility and personnel transport, and time-sensitive business trips within the western United States and adjoining regions. Avionics and interior specifics are consistent with Citation II executive fits but are not itemized here; maintenance considerations follow the twin-engine Pratt & Whitney JT15D-4 powerplant regime and the airframe’s 1992 manufacture vintage, affecting inspection cycles and potential retrofits.

The Cessna 550 Citation II occupies the light corporate jet segment as a capable short-to-medium-range business aircraft, offering transregional capability with a relatively high cruise speed and 43,000 ft service ceiling. In the market, Citation IIs appeal to corporate operators seeking efficient point-to-point travel with an eight-seat executive cabin; demand is driven by utility and corporate owners as well as charter operators. Maintenance and resale considerations for a 1992-built airframe typically weigh engine time, avionics modernization, and interior condition relative to remaining useful life and mission requirements.
