N81EX

This article covers a specific Embraer ERJ-145EP airframe, carrying U.S. registration N81EX. The aircraft was built in 1998 by Embraer S.A. with manufacturer serial number 145053 and is recorded as owned by EXODUS AIRCRAFT LLC of Wilmington, DE, US. The airframe is a 55-seat regional jet in the fixed-wing multi-engine category and is listed on the U.S. registry as US-registered. Notable administrative points include its original build year 1998 and the current ownership entry showing EXODUS AIRCRAFT LLC, indicating a clear chain pointing to a Delaware-based limited liability company as the custodial owner.

The airframe configured as an Embraer ERJ-145EP typically supports a single-class 55-seat regional layout; for this specific airframe the seating count is 55, reflecting standard ERJ-145 cabin density for short- to medium-range regional operations. With a cruise speed of 453 kts and a range of 1,200 nm, the aircraft is suitable for high-frequency regional hops and charter missions within continental markets. The powerplant package of 2× Allison AE 3007A1/1 engines, each rated at 7,580 lbf, supports operations up to a service ceiling of 37,000 ft, enabling efficient climb and cruise profiles for route structures typical to 50–70 seat regional services. Maintenance considerations for this airframe follow the ERJ-145EP fleet norms, including engine-specific line and shop checks consistent with its serial 145053 and age since 1998 manufacture.

The Embraer ERJ-145EP occupies the regional jet niche for sub-100-seat markets, offering a balance of speed (453 kts) and short-to-medium range capability (1,200 nm) powered by the Allison AE 3007 family. Competing types in this segment historically include regional jets from Bombardier and other Embraer variants; demand is often highest among regional carriers and charter operators seeking 50–60 seat aircraft. For resale and maintenance, operators of airframes like N81EX must account for lifecycle factors tied to a 1998 build, including airframe fatigue management, avionics update cycles, and engine overhaul schedules for the 7,580 lbf AE 3007 units.
