N521SY

This airframe, registered as N521SY, is an Embraer-built regional jet delivered in 2022 with manufacturer serial number 17000906. The airframe is owned by SKYWEST AIRLINES INC, a corporate operator based in Saint George, UT, US, and is registered in the US. FAA-derived records report a high-density single-class seating configuration for this specific airframe. The entry of this aircraft into the SKYWEST fleet in 2022 represents its initial operator assignment and primary commercial use within regional operations. No alternate ownership or notable registry actions beyond the recorded corporate registration are published in the supplied data.

The airframe is fitted in a high-density single-class cabin layout with 88 seats as reported in FAA-derived records, matching the typical regional carrier seating plan for short- to medium-haul missions. Avionics fit is listed as Honeywell Primus Epic (typical E175 operator fit), supporting modern flight-deck functionality and regional airline operational requirements. Typical missions for this aircraft profile include frequent short- and medium-range sector rotations within a regional network, operating out of the owner’s base in Saint George, UT, US. Maintenance considerations for this specific aircraft align with common E175 operator practices, driven by its two CF34-8E5 turbofans and high-utilization regional schedule.

As an Embraer ERJ-175LR, this airframe sits in the regional jet performance niche offering extended-range capability relative to standard E175 variants, enabling transcontinental regional sectors within its 2,200 nm range and a service ceiling up to 41,000 ft. Competing models for the same mission typically include other 70–90 seat regional jets; demand among regional carriers favors aircraft with high-density seating and reliable CF34-series engines. Resale and maintenance considerations for this airframe will reflect its 2022 build date, corporate ownership by SKYWEST AIRLINES INC, and typical avionics and engine commonality with other E175s in regional airline service.
