N257SY

This airframe, registered as N257SY, is an Embraer-built regional jet identified as the Embraer ERJ-170-200LR (E175LR) completed in 2017 with manufacturer's serial number 17000648. The airframe is owned by the corporation SKYWEST AIRLINES INC, based in St George, UT, US, which operates the type in regional airline service; no separate historic ownership transfers beyond corporate registry are recorded here. The airframe holds a US civil registration and is maintained to operator standards for high-utilization regional operations. Notable registry actions: Not published.

The airframe is fitted in a high-density single-class configuration with 88 seats as an operator-configured layout intended for short- to medium-haul regional trunk routes. Avionics are in the typical Embraer E175 fit with Honeywell Primus Epic (typical E175 fit) suites, supporting advanced flight management, flight deck situational awareness and airline operational integration. With a 2,200 nm range and a cruise speed of 448 kts, this installation is optimized for frequent sector rotations between hub airports and thin to mid-density city pairs, aligning with SkyWest’s network role. Maintenance and operational considerations for this specific airframe follow regional airline heavy-utilization cycles and OEM-recommended shop visits for the CF34-8E5 engines and airframe aging items.

The Embraer ERJ-170-200LR (E175LR) occupies the upper end of the 70–90 seat regional jet class, offering longer-range capability relative to earlier regional types while retaining regional airline economics. It competes with stretched regional variants from other manufacturers in airline markets seeking 80–90 seat capacity with transregional range. Buyer and lease demand for in-service E175LR examples typically prioritizes airframes with low-cycle, well-documented maintenance records and commonality with existing fleet avionics such as the Honeywell Primus Epic fit; resale considerations emphasize engine CF34-8E5 life limits and remaining structural checks consistent with the airframe’s 2017 build year.
