N889SH

This entry covers airframe N889SH, a 1984-built Cessna 501 Citation I/SP with manufacturer serial number 501-0681. The airframe is registered in the United States and is owned by the corporation REDFISH HOLDINGS INC, based in King Salmon, Alaska. The aircraft reflects typical late-production Citation I/SP attributes for its year — single-pilot certification, light corporate configuration and regional ownership — and its registry and ownership details point to corporate use from a remote Alaskan base. Ownership is held by REDFISH HOLDINGS INC in King Salmon, AK, and there are no additional public notations of ferry flights or major registry actions provided in the available data.

The airframe is configured in a single-pilot certified executive layout and, depending on owner fit or interior modifications, typically accommodates 6–8 passengers. Avionics are listed as the Collins Pro Line suite as fitted, with the caveat that avionics packages can vary by retrofit or upgrade on individual airframes. From its King Salmon, AK operator base, missions for this aircraft type and configuration would center on regional corporate transport, ad hoc charters, and point-to-point travel where relatively short runway performance and single-pilot operation reduce operating crewing complexity. Maintenance considerations for this specific airframe reflect standard Citation I/SP practices for mid-1980s jets, including attention to JT15D engine hot-section service intervals and airframe corrosion inspection given operation in northern maritime environments.

The Cessna 501 Citation I/SP occupies the light business jet niche of the early 1980s, offering modest transcontinental range and high cruise speed for its class. Competing models in the period and secondary market include other light jets with similar capacities and single-pilot capability; buyer demand often centers on owner-operators and small corporations seeking efficient short- to mid-range point-to-point travel. Resale and maintenance considerations hinge on avionics modernization (Collins Pro Line suites are commonly upgraded), engine overhaul status of the two JT15D powerplants, and the airframe’s inspection history, all of which materially affect valuation for a 1984 Citation I/SP airframe such as N889SH.
