N445YX

This airframe, registered as N445YX, is an Embraer-built regional jet of the E-Jet family, specifically the Embraer 175LR (ERJ-170-200LR), manufactured by Embraer S.A. in 2015 and bearing serial number 17000455. The aircraft is owned by Republic Airways Inc (a corporation headquartered in Indianapolis, IN, US) and is maintained and operated within US registry parameters. Ownership has remained with Republic Airways Inc as the named corporate owner, with the airframe typically deployed in regional passenger service; no other registry actions or transfers are published in the provided data.

The subject aircraft is configured with a typical regional four-abreast cabin layout, 4-abreast (2-2), and is commonly operated in a dual-class US regional service arrangement of 12 first + 64 economy seats depending on operator configuration. Avionics fit for this E-Jet is the typical Honeywell Primus Epic, supporting modern regional airline operational requirements. In service with Republic Airways Inc, the airframe is used on short- to medium-range regional missions where its 2,200 nm range and 480 kts cruise enable efficient frequent-turn rotations; maintenance considerations follow standard E-Jet practices for CF34-powered regional jets, and operator-dependent cabin fit may affect turnaround and cleaning procedures.

The Embraer 175LR occupies the mid-size regional jet niche within the E-Jet family, offering higher capacity than regional turboprops and lower operating cost per seat than many larger narrowbodies on short and thin routes. Competing types include other E-Jets and similar regional jets from competing manufacturers targeting US regional operators. Buyer and lease demand for this variant typically reflects airline network needs for 70–90 seat regional markets; maintenance and resale considerations hinge on CF34 engine support, airframe cycle history, and operator configuration, all relevant to an airframe like N445YX in US regional service.
