N138SY

This entry describes airframe N138SY, an Embraer ERJ-170-200LR (designation E175LR) manufactured by Embraer S.A. in 2015 with serial number 17000466. The airframe is owned by SKYWEST AIRLINES INC, a corporation registered in St George, UT, US, and is maintained and operated in the US national registry under US registration. As a high-density Long Range (LR) variant delivered mid-decade, the airframe typically reflects fleet-standard maintenance and utilization profiles for regional jet operators; ownership by a major regional carrier places this airframe in continuous commercial service cycles and scheduled maintenance programs.

The aircraft is outfitted in a high-density airline layout configured for up to 88 single-class seats typical of the LR configuration, optimized for regional trunk routes and high-seat-density shuttle services. In operational terms the E175LR variant is used on medium-range sector work where a combination of seat capacity and extended stage length is required; this airframe’s 2,200 nm range and 447 kt cruise allow transregional missions without payload penalties common to shorter-range regional types. Registered to SKYWEST AIRLINES INC in St George, UT, the aircraft is likely scheduled from primary hubs consistent with the operator’s network and maintained to airline shop visits and engine shop cycles for the GE CF34-8E5 powerplants. Cabin amenities follow airline-standard fittings rather than bespoke VIP modifications; maintenance considerations center on regional utilization rates and hot-section inspections driven by frequent short-sector cycles.

The Embraer ERJ-170/175 family occupies the 70–90 seat regional jet niche where efficiency, runway performance, and pilot commonality are competitive drivers. The E175LR traded off modestly greater range for increased payload capability compared with base ERJ-170 variants, positioning it against competitors such as stretched regional jets and smaller narrowbodies in airline fleet plans. For buyers and lessors, considerations include remaining airframe life from a 2015 build, spare parts support for GE CF34-8E5 engines, and residual value influenced by single-class high-density configurations that may require conversion for different market roles.
