N921FJ

This airframe, registered as N921FJ, is a 2004-built Bombardier airliner manufactured by Bombardier Inc. and carries manufacturer serial number 15021. It is recorded as being owned by the corporation Regional One and is registered in the US. The airframe's configuration and past cabin density indicate a shift in commercial role, with the registration and configuration history reflecting a reconfiguration from a high-density layout to a dual-class layout under current ownership. Not published registry actions and valuation details limit public tracing of leasing or recent transaction history.

This specific CRJ-900ER is presented in a C9Y70 (70-seat dual-class configuration; previously Y86 high-density) cabin layout, indicating its current role favors regional services with a premium/comfort element over earlier high-density operations. As a 70-seat regional jet with trans-regional range of 1,553 nm and a cruise speed of 447 kts, typical mission profiles include short- to medium-haul routes between secondary and primary airports, high-frequency shuttle services, and thin trunk routes where frequency and regional economics are prioritized. Avionics fit and exact onboard amenities are not published for this airframe; maintenance considerations follow the CRJ-900ER family pattern with twin CF34-8C5 engines, requiring OEM-recommended shop visits and component exchanges commensurate with a 2004 serial build. Operator base specifics beyond corporate ownership are not published.

The airframe belongs to the Bombardier CRJ-900ER family (CL-600-2D24), a stretched member of the CRJ series occupying the 70–90 seat regional market niche. With a service ceiling of 41,000 ft, efficient twin CF34 powerplants and a practical range of 1,553 nm, the type competes with regional variants of Embraer E-Jets and smaller narrowbodies for frequency-focused operators and regional airlines. Buyer and charter demand for a 2004-built airframe is influenced by remaining fatigue life, maintenance status, and cabin configuration—the documented shift from Y86 to C9Y70 can improve appeal to carriers seeking a two-class product, while resale and maintenance considerations follow typical lifecycle patterns for mid-2000s CRJ-900ER airframes.
