N157SY2016 Embraer ERJ-175LR

Overview

This entry covers airframe N157SY, an Embraer ERJ-175LR built in 2016 with manufacturer's serial number 17000558. The airframe is owned and operated by Skywest Airlines Inc, a corporation based in St George, UT, US, and is registered in the US.

Operations & Cabin

The airframe is registered and configured for 88 seats in a high-density single-class layout, consistent with the operator-configurable nature of the E175 family; the operator commonly configures the model between 76 dual-class and 78-88 single-class, and this specific airframe is registered at the upper end of that spectrum. Typical mission profiles for this aircraft under its operator include short- to medium-haul regional airline routes where a high-density single-class layout maximizes passenger throughput. The avionics fit is reported as Honeywell Primus Epic as typical for E-Jets, though operator-specific fit may vary, and maintenance considerations follow regional airline practices for two-engine CF34-powered regional jets. Ownership by Skywest Airlines Inc implies integration into the operator’s regional fleet operations and maintenance regime based from St George, UT.

Model & Market Context

The Embraer ERJ-175LR occupies a performance niche as a stretched regional jet offering higher seat counts and range compared with earlier regional types, suited to thin mainline and dense regional markets. Competing models in this sector include other 70-90 seat regional jets and high-density narrowbodies adapted for regional routes. Resale and maintenance considerations for this airframe reflect its 2016 vintage, CF34-8E5 propulsion, and its operator-configured high-density certification which can influence valuation and reconfiguration cost for different operators.
