N511WS

This entry covers airframe N511WS, a Cessna Citation I/SP built in 1979 with serial number 501-0136. The airframe is registered in the United States and is owned by MCBRIDE AVIATION LLC, an LLC based in Longview, TX, US, which serves as the operator/home base for this specific jet. The airframe is a fixed-wing multi-engine business jet reported in listings with operator-upgraded avionics and a typical executive cabin; public records and sales listings place the estimated market value at $675,000. No other registry actions or change-of-owner events are published beyond the current ownership and typical retrofit history noted in operator listings.

The cabin for N511WS is reported as a typical executive layout described as a 5-place club with a forward galley and aft lavatory, though the specific configuration may vary by operator and interior refurbishment history. Avionics fit varies with retrofit and operator preference; listings for this airframe commonly cite installations such as Garmin GTN 750W, GTX-33 transponder and GMA350 audio panel as part of operator-upgraded avionics. Typical missions for this airframe type and configuration include short- to medium-range executive transport and on-demand charter work within continental ranges consistent with a 1,328 nm capability and cruise speeds near 322 kts. Maintenance considerations for this specific jet reflect the common retrofit and upgrade practice among Citation I/SP operators; avionics and interior upgrades are frequently performed to sustain operational utility and resaleability.

The airframe belongs to the single-pilot capable Cessna Citation I/SP family (Model 501), positioned as an entry-level business jet offering modest range and efficient short-field capability for its era. In the current market, older Citation I/SP airframes like N511WS compete with other light jets for owners seeking lower acquisition cost and simple operating profiles rather than long-range capability. Buyer and charter demand tends to focus on airframes with documented upgrades—avionics, interior, and engine maintenance—so examples reporting common retrofits (as this airframe does) can command stronger interest; however, maintenance, parts availability and avionics modernization remain key considerations affecting resale and operational economics.
