N645QX

This entry covers airframe N645QX, an Embraer regional jet built in 2018 with manufacturer serial number 17000768. The airframe is a Embraer 175LR (ERJ-170-200LR / E175) manufactured by Embraer S.A. and is owned by HORIZON AIR INDUSTRIES INC (a corporation based in Seattle, WA, US). The type is registered in the US and has been operated in a Horizon/Alaska service configuration; the aircraft is certified/registered with up to 88 seats, reflecting its dual-use as both a 76-seat operator layout and a high-density transport option. Condition and valuation specifics are not published for this individual airframe.

The aircraft is operated in a Horizon/Alaska service operator layout configured as 76-seat dual-class (12 First, 64 Main) while retaining certification for up to 88 seats for high-density deployments. Avionics fit and specific in-service modificiations for this airframe are not published; routine configuration reflects Embraer regional standards and operator-specific cabin furnishings used on short- to medium-haul regional routes. Typical mission profiles for this airframe include high-frequency regional shuttle and point-to-point routes within the continental United States, leveraging its 2,200 nm range and cruise speed to serve longer regional sectors and rapid turnarounds. Maintenance considerations for this airframe follow common practices for GE CF34-powered E175s, emphasizing lifecycle inspections of the CF34-8E5 engines and structural checks consistent with the 2018 build standard.

The airframe is a member of the E175 family produced by Embraer S.A., positioned in the regional jet niche as a stretched, longer-range regional variant. With a cruise of 480 kts and a 41,000 ft ceiling, the E175LR targets operators needing regional capacity with enhanced stage lengths compared with smaller regional types. Market demand typically centers on airlines replacing turboprops or upgauging smaller regional jets; resale and maintenance considerations include CF34 engine support, fleet commonality for Horizon/Alaska operators, and the dual-role certification that allows conversion between the 76-seat operator layout and 88-seat high-density use.
