ERJ Regional Jet Family

Proven Regional Jets With Worldwide Operating History

The Embraer ERJ 135 and ERJ 145 belong to one of the best-known regional jet families in commercial aviation.

The ERJ 135 provides a shorter fuselage and lower passenger capacity, while the ERJ 145 extends the same basic aircraft architecture for up to 50 passengers.

Both aircraft use rear-mounted twin turbofan engines, a T-tail configuration and a narrow regional-jet fuselage, giving operators significant family commonality.

AeroX supports regional aircraft operators with maintenance, structural repairs, avionics upgrades, aircraft modifications and worldwide technical services.

Regional Jet Operations

Supporting High-Cycle Regional Aircraft

Regional jets frequently operate demanding schedules involving multiple flights, takeoffs and landings during a single operating day.

High-cycle aircraft operations can make structural condition, landing-gear-area structures, fuselage condition, doors, flight-control systems and maintenance reliability particularly important as aircraft accumulate years of service.

AeroX can support maintenance and modification work scopes designed around the individual ERJ aircraft's condition, configuration and operating requirements.

Scheduled aircraft inspections
Structural condition assessment
Aircraft skin repairs
Corrosion repair
Avionics troubleshooting
Electrical modifications
Cabin modernization
Worldwide technical support
37–50

Regional Capacity. Jet Performance.

The ERJ family brought jet speed and performance to lower-capacity regional airline markets.

The ERJ 135 can accommodate up to 37 passengers, while the ERJ 145 increases capacity to 50 seats.

Their common architecture makes the family especially useful for operators managing mixed regional aircraft fleets.

Aircraft Propulsion

Rolls-Royce AE 3007-Series Powered Regional Jets

ERJ 135 and ERJ 145 aircraft use variants of the AE 3007 turbofan engine family.

FAA registration data for active EMB-135 and EMB-145 aircraft continues to identify AE 3007-series engines on the platform.

Engine model varies according to aircraft variant and configuration, including AE 3007A-series installations.

AeroX can support surrounding aircraft requirements such as nacelle structures, pylons, electrical systems, wiring, troubleshooting and aircraft modification work within an approved technical scope.

AE3007

Twin Rear-Mounted Turbofan Architecture

Two aft-mounted turbofan engines are one of the defining visual and engineering features of the ERJ family.

The configuration leaves the wing free of engine pylons and gives the aircraft the distinctive T-tail regional-jet layout.

ERJ

Mature Regional Fleet

Many active ERJ 135 and ERJ 145 aircraft were produced during the late 1990s and early 2000s.

Continued operation can require attention to corrosion, previous structural repairs, wiring condition, aging components and legacy avionics.

Aging Aircraft Support

Extending the Useful Life of ERJ Aircraft

A mature regional jet may have accumulated thousands of cycles, multiple repairs and decades of aircraft modifications.

Operators may need structural repairs while simultaneously upgrading avionics, communications, electrical systems or cabin equipment.

AeroX's multi-discipline approach allows maintenance, structures, avionics and modifications to be coordinated within a single aircraft project when appropriate.
