N173SY

This airframe, registered as N173SY, is an Embraer ERJ-175LR built in 2015 with manufacturer serial number 17000486. The aircraft is owned by SKYWEST AIRLINES INC, a corporate operator based in St George, UT, US; the airframe appears in FAA records under that corporate ownership and has been used in regional airline service. The registration is listed as US and the airframe has been maintained and operated under SkyWest-type regional network deployments, including service under SkyWest/Alaska regional agreements where interior configuration has been operator-adapted. No separate commercial valuation figure is published in the supplied data.

FAA records list the cabin as 88 seats in a high-density layout, while typical SkyWest or Alaska regional service for this airframe is noted to use a 76-seat dual-class layout, reflecting operator-dependent interior installations. The avionics fit for this airframe is listed generically as Honeywell Primus Epic, with actual fit and equipment varying by operator and installation choices. Typical mission profiles for this specific ERJ-175LR include short- to medium-haul regional routes operated from SkyWest’s bases, connecting larger hub airports with smaller city-pair markets; this airframe’s range and cruise speed suit high-frequency regional shuttle and thin-route services. Maintenance considerations reflect standard regional airline practices for CF34-powered Embraer 175s, with operator-specific maintenance programs and modifications driven by SkyWest fleet commonality and contractual service obligations.

The airframe belongs to the Embraer ERJ-175LR family, a stretched regional jet offering improved capacity and range over earlier ERJ-170 series variants and aimed at replacing turboprops or small narrowbodies on regional trunk routes. Performance characteristics—1,800 nm range, 473 kts cruise, and a 41,000 ft ceiling—position it against competing 70–90 seat-class types from Bombardier/De Havilland and small narrowbody used aircraft markets. Buyer and charter demand for the ERJ-175LR is driven by regional carriers seeking stage-length flexibility and commonality with CF34-powered fleets; resale and maintenance considerations center on airframe hours, the CF34 engine program support, and interior reconfiguration costs when shifting between high-density and dual-class operator fits.
