N439YX

This airframe, registered as N439YX, is an Embraer-built regional jet of the ERJ-170/175 family delivered in 2014 with manufacturer serial number 17000434. The aircraft is owned and operated by Republic Airways Inc, a corporation based in Indianapolis, IN, US, and is registered in the US. Recorded on the U.S. civil aircraft registry under the owner's corporate registration, the airframe conforms to the operator's typical configuration and service pattern. Condition and valuation notes for this specific serial are not published beyond its in-service operator assignment.

The airframe operates in a dual-class layout configured by the operator as 76-seat (approx. 12 business / 64 economy), matching Republic Airways’ typical regional narrowbody interior for higher-density short- to medium-haul missions. Avionics are fitted with the Honeywell Primus Epic integrated flight deck, supporting advanced navigation and common regional airline operational procedures. Typical mission profiles for this aircraft include short- to medium-range regional routes within a 2,200 nm operational radius, optimized for high-frequency shuttle and feeder services from the operator’s Indianapolis base. Maintenance and operational considerations follow Embraer’s regional jet schedules and Republic’s operator maintenance program; any unique airframe-specific modifications beyond the published configuration are not disclosed.

The airframe is an Embraer 175LR (ERJ-170-200LR), representing the longer-range, higher-capacity variant of Embraer’s ERJ-170/175 family designed for regional carriers seeking 70–80 seat capability with trans-regional flexibility. In market terms, the 175LR competes with similarly sized regional jets and stretched regional variants from other manufacturers, offering a balance of fuel efficiency, range, and passenger capacity suitable for airline feeders and thin mainline routes. Buyer and resale demand is typically driven by regional network needs and fleet commonality; maintenance and resale considerations emphasize engine type (CF34-8E) lifecycle, avionics commonality (Honeywell Primus Epic), and the airframe’s 2014 build year and serial provenance.
