N13989

This entry concerns airframe N13989, an Embraer-built regional jet delivered in 2000 with manufacturer serial number 145271. The type for this airframe is the Embraer EMB-145LR (ERJ-145LR) produced by Embraer S.A.. The aircraft is registered in the United States and is owned by ExpressJet Airlines, a United States-based corporation. The airframe is a fixed-wing multi-engine regional jet configured and operated in a single-class layout for short- to medium-haul services.

The airframe operates with a single-class regional cabin, typically arranged as 55 economy seats in a 1–2 abreast configuration optimized for high-density regional schedules. As an LR (Long Range) variant of the ERJ-145 family, this specific aircraft is used in typical regional airline missions including short- to medium-range point-to-point services that match its 1,550 nm range and high cruise speed. Registered and operated under U.S. registry as N13989, routine operations reflect airline-style utilization patterns, focusing on quick turnarounds and frequent daily cycles; maintenance considerations align with regional-jet regimes for twin AE 3007A1-powered fleets.

The Embraer EMB-145LR (ERJ-145LR) family occupies the regional jet niche between commuter turboprops and larger narrowbody jets, offering relatively high cruise speed (515 kts) and modest long-range capability for point-to-point regional routes. Competing models historically include other 50-seat regional jets and high-performance turboprops; demand centers on regional carriers and charter operators seeking economical 50–60 seat capacity. Maintenance and resale considerations for this LR-configured airframe reflect typical market practice for AE 3007A1-powered ERJ-145s—parts commonality, lifecycle maintenance scheduling, and fleet standardization heavily influence operator economics.
