N166SY 2016 Embraer 175LR

Overview

This airframe, registered as N166SY, is an Embraer 175LR (marketed within the ERJ-170/200LR family) built in 2016 with manufacturer serial number 17000615 by Embraer S.A.. The aircraft is recorded as owned by Skywest Airlines Inc, a corporation based in St George, UT, US, and carries a United States registry. Entered into the U.S. registry as a SkyWest asset in 2016, the airframe is noted in records with a high-density cabin allocation and has been deployed in regional airline service under operator configurations that may be altered from the registry listing.

Operations & Cabin

The registry for N166SY lists a high-density cabin of 88 seats; however, operator deployments, particularly when flying for United Express, commonly use a 76-seat dual-class fit, and the actual on-aircraft fit may vary following operator retrofits or interior reconfigurations. Avionics fit for this airframe is the typical E-Jets suite, listed as Honeywell Primus Epic, supporting modern regional operational cycles and common airline flight-deck procedures. Operationally the airframe suits short-to-medium regional missions consistent with a 2,200 nm range and a cruise of 448 kts, and its ceiling of 41,000 ft aligns with standard regional jet flight profiles. Maintenance considerations are consistent with the CF34-8E5 engine series and E-Jets airframe support networks; specific maintenance history and condition statements are held on the operator’s records.

Model & Market Context

The Embraer 175LR derivative occupies the regional jet niche between smaller 70-90 seat regional types and larger single-aisle mainline aircraft, offering airlines density options up to 88 seats or lower-density dual-class fits for premium regional service. Competing models in similar mission profiles include other E-Jet variants and smaller narrowbodies adapted for regional use; demand typically centers on regional feeders and capacity-flexible schedules. From a resale and maintenance perspective, engines GE CF34-8E5 and the Honeywell avionics commonality aid fleet interoperability, while operator-specific interior retrofits can affect valuation and remarketing timelines.
