Airbus Final Assembly Line Adapts for A350 Freighter Production

As Airbus prepares for the final assembly of the A350 Freighter (A350F), the first large parts are already taking shape at Airbus Atlantic and Airbus Aerostructures facilities in France and Germany. Teams in Toulouse are busy getting ready for assembly activities, set to begin next year.

The A350F is the third version of the A350 family. While it shares many common features with the passenger versions, the freighter has some significant differences. These include structural reinforcements, such as stronger center-wing-box floor beams, as well as changes in size, shape, and equipment.

The A350F’s fuselage is longer than the A350-900 but shorter than the A350-1000, providing an optimal cargo space. It also has the largest main-deck cargo door ever installed on a commercial aircraft, located on the left side of the rear fuselage.

Inside, the A350F is designed to carry large volumes of cargo. The full-length cargo-loading system supports containers and pallets, and the sidewalls are reinforced with windowless linings. A special 9g cargo barrier wall is located at the front, alongside a dedicated crew rest compartment and a courier area.

To accommodate these changes, Airbus is adapting the assembly stations at the Roger Béteille A350 FAL, where the A350-900 and -1000 are currently produced. The new geometry of the A350 Freighter requires adjustments to the jigs and tools used in the assembly line.

Additionally, the production stations are being modified to allow staff easier access to both the interior and exterior, especially around the large cargo door frame. At Station 40, where the wing assembly takes place, a new platform plug is being tested to lift the cargo-loading system and trolleys closer to the main deck entrance during assembly.

One of the standout features of the A350 Freighter is its impressive range. With a maximum takeoff weight of about 280 metric tons and a payload capacity of up to 100 metric tons, it can operate on long-haul routes efficiently. This makes it ideal for global cargo transport, compare to the a350 vs 777, this will reducing the need for frequent refueling stops.

The A350 Freighter’s cargo hold is also designed for flexibility, with the capacity to carry up to 109 tons of cargo. It has a wide, flat floor for easy loading and unloading and offers a total volume of 1,500 cubic meters, making it suitable for pallets, containers, and oversized items.

In addition to the physical changes to the assembly stations, Airbus is also adapting the production methods. The goal is to make the transition between building freighter and passenger versions of the a350 aircraft as smooth as possible, with minimal disruption. This approach ensures that production teams will be able to efficiently switch between the two versions once serial production begins.

Why Embraer’s E175-E2 Faces Challenges in the U.S. Market

Embraer, a renowned Brazilian aircraft manufacturer, has a strong reputation for building regional jets that connect smaller cities worldwide.

While its aircraft are widely used in various countries, the United States imposes restrictions on certain Embraer models, particularly the E175-E2. In this article, we’ll explore why this aircraft is blocked from entering the U.S. market.

The Embraer E175 vs. E175-E2

The E175 is allowed in the U.S. and is a popular choice for regional airlines operating short-haul routes.
The E175-E2, a more advanced and fuel-efficient version, faces restrictions due to scope clauses.

1. Scope Clause Restrictions

Scope clauses are agreements between major U.S. airlines and pilot unions that limit the size and weight of aircraft used by regional carriers.

These clauses cap the maximum takeoff weight (MTOW) at 86,000 pounds.
The E175-E2 exceeds this limit with an MTOW of 98,120 pounds (44,600 kg), making it ineligible for regional operations.

2. Fleet Compatibility

U.S. regional carriers typically operate under agreements that favor aircraft compliant with scope clauses.

The original E175 meets these criteria, making it easier to integrate into existing fleets.
The E175-E2, despite its improved efficiency and longer range, is considered incompatible with current contracts.

3. Market Dynamics

Modifying scope clauses would require complex negotiations between airlines and pilot unions, a process that can be time-consuming and contentious.

Major airlines have shown little interest in pushing for these changes, especially with other compliant aircraft available.
The lack of demand has led Embraer to suspend the development of the E175-E2 in February 2022.

Similar Challenges Faced by Competitors

Embraer isn’t the only manufacturer affected by scope clauses.

Mitsubishi’s SpaceJet program was similarly halted in 2023 due to the same restrictions.
Larger regional aircraft like the E190-E2 (MTOW: 124,340 lbs) are also excluded from regional contracts, further limiting options.
In the U.S., airline and pilot union agreements restrict regional carriers to aircraft with a maximum of 76 seats or a maximum takeoff weight (MTOW) of 86,000 pounds (39,000 kg).

The Embraer E175-E2, however, exceeds these limits, offering seating for up to 90 passengers in a single-class layout and an MTOW of 98,120 pounds (44,600 kg).
Due to these restrictions, Embraer suspended the E175-E2 program in February 2022, citing scope clause limitations as the primary reason for pausing development.

The Decline of Small Regional Jets

The U.S. market is shifting away from smaller, 50-seat regional jets.

In 2019, there were 660 active 50-seat regional jets.
By November 2024, this number had dropped to 260, creating a gap in the regional aviation market that remains unfilled.

Impact on U.S. Aviation

The inability to introduce newer, more efficient regional jets like the E175-E2 is impacting both airlines and manufacturers:

U.S. airlines must adjust flight routes and seating configurations to accommodate older aircraft models.
Boeing, a domestic competitor, also faces challenges as demand shifts towards larger aircraft, reducing regional jet sales.

Conclusion

While the E175-E2 is permitted and operational in many countries, it remains blocked in the U.S. due to regulatory limitations. This situation highlights the pressures faced by domestic manufacturers and airlines as they struggle to balance efficiency, regulations, and market demands.
