RESEARCH NOTES

About N157SY

Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.

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.
