N727EF

This airframe, registered as N727EF, is a 1985-built Cessna S550 Citation S/II with serial number S550-0043. It is operated and owned by Illinois Orthopedic Network LLC, a corporate owner based in Chicago / Wheaton, IL, US, and is registered in the US civil registry. The airframe carries a valuation placed at $856,000, reflecting its mid-1980s build year, two-engine configuration, and executive six-place cabin; registry and ownership records indicate corporate operation rather than commercial charter use.

The interior of N727EF is configured in a 6-place executive layout (forward club seating typical), optimized for short- to mid-range corporate missions. Avionics aboard this airframe follow the common fitment/retrofit for S/II variants with the Collins Pro Line II, supporting conventional corporate navigation and communications for its era. With a maximum cruise of 403 kts and a practical mission range of 1,998 nm, the jet is suited to transcontinental point-to-point trips and regional business travel from its operator base in Chicago / Wheaton, IL. Maintenance considerations for this specific airframe center on age-related airframe systems and the continued support and overhaul requirements for the Pratt & Whitney Canada JT15D-4B turbodfan engines.

As a member of the Cessna S550 Citation S/II family, this airframe occupies the light, twin-engine corporate jet niche, balancing modest cabin capacity with efficient short- to medium-range capability and a 43,000 ft service ceiling. Market demand for such vintage S/II examples is typically driven by owner-operators and small corporations seeking economical executive transport; resale and maintenance outlooks are influenced by installed avionics like the Collins Pro Line II, engine time on the JT15D-4B units, and the aircraft’s assessed value of $856,000.
