This entry covers airframe N121SY, an Embraer 175LR (ERJ-170-200LR) built in 2014 with manufacturer serial number 17000430. The aircraft is owned by SKYWEST AIRLINES INC, a corporate owner located in St. George, UT, US, and is certificated on the US registry. Owned and operated within the SkyWest fleet and based out of St. George, Utah, the airframe’s type certification supports an airline-fit seating arrangement while the registry lists a higher certification limit. Notable registry detail for this specific airframe is the recorded certification seating of 88, while operator cabin fit is commonly recorded as a United Express 76-seat layout; valuation and condition specifics for this individual airframe are Not published.

The aircraft is typically operated in a regional airline role under SkyWest’s operations; the common airline fit for the type on this airframe is a United Express 76-seat layout (C12Y64), configured as 12 business and 64 economy seats, while registry certification permits seating up to 88. Mission profiles for this airframe center on short- to medium-range regional routes within a 2,200 nm capability and cruise dispatch at approximately 450 kts, serving point-to-point scheduled services and high-frequency regional sectors. Maintenance considerations follow Embraer and GE CF34-8E5 program schedules typical of commercial regional fleets, with operator base support in St. George, Utah, for line maintenance and scheduled checks.

The Embraer 175LR occupies a performance niche as a larger regional jet in the E-Jet family, offering extended-range capability and a higher seat count relative to smaller regional types. It competes with similar regional jets in airline fleet planning where carriers seek a balance of passenger capacity and range for thin- to medium-density routes. Buyer and resale demand for the type reflect airline network needs for 70–90 seat class aircraft, and maintenance or resale considerations for this airframe incorporate the GE CF34-8E5 engine maintenance track and the aircraft’s 2014 build year and registry condition.
