DALLAS – The European Union Aviation Safety Agency (EASA) has issued the Type Certificate for the Airbus A321XLR, using Pratt & Whitney GTF engines. 

This follows EASA’s certification of the CFM LEAP-1A-powered A321XLR in July 2024.

Comparable to other wide-body aircraft, the A321XLR provides Xtra Long Range. With a flight time of up to 11 hours and a range of up to 4,700nm, the type can connect destinations such as “New York to Rome, London to Vancouver, Delhi to London, and Sydney to Kuala Lumpur.”

Airbus boasts the type that introduces the flexibility to add capacity, to open new routes, or even continue operating existing ones when demand is variable. The A321XLR, the latest member of the A320 Family, includes the manufacturer’s new Airspace cabin in all classes.

The type redefines narrow-body operations by extending range capabilities with next-generation engines enabling long-haul efficiency. Central to this evolution are the Pratt & Whitney Geared Turbofan and CFM International's engines.

The first A321XLR completed its maiden flight in June 2022. This was followed by an extensive test program involving three test aircraft. The A321XLR entered service in 2024. More than 500 Airbus A321XLRs have been ordered so far.

The first customer A321XLR aircraft with P&W engines will enter into service later this year.

Christian Scherer, CEO Commercial Aircraft at Airbus, said, "The A321XLR already displays its great versatility crossing the Atlantic in daily operations. With the certification and entry-into-service of the GTF-powered A321XLR, we will see more operators introduce this game-changing aircraft. It is also good news for our customers’ passengers who will benefit from the convenience of new direct city-to-city connections with a heightened level of cabin comfort.”

Evolution of the A321XLR, Propulsion Systems

The Airbus A321XLR, launched in 2019, was designed to address the growing demand for long-range, single-aisle aircraft capable of transcontinental and transoceanic routes.

By integrating a rear center fuel tank (RCT) into the fuselage, the aircraft achieves a range of 4,700 nautical miles (8,700 kilometers), enabling non-stop flights such as Madrid to Boston while maintaining narrow-body economics.

This design innovation introduced unique engineering challenges, particularly regarding fuel tank safety and structural integrity.

The A321XLR’s efficiency hinges on its engines: the Pratt & Whitney GTF and CFM LEAP-1A. Both engines leverage cutting-edge technologies to reduce fuel burn by 16–20% compared to previous-generation models, with corresponding reductions in CO₂ emissions.

The GTF’s geared fan architecture decouples the fan and turbine speeds, optimizing efficiency across flight phases, while the LEAP-1A employs advanced materials and combustion dynamics to achieve similar gains.

Rear Center Fuel Tank Challenge

Like the GTF variant, the LEAP-1A-powered A321XLR faced scrutiny over the RCT’s integration. As reported by aviationweek.com, EASA and Airbus resolved debates about fire protection by redesigning the tank’s insulation and adding weight-saving measures elsewhere in the airframe. These modifications ensured compliance with fire containment regulations without eroding the aircraft’s range guarantees

The RCT’s integration into the A321XLR’s fuselage necessitated novel regulatory approaches. Traditional auxiliary fuel tanks, housed in cargo holds, are isolated from the airframe, but the RCT’s structural integration raised concerns about fire propagation and structural failure during post-accident scenarios.

According to P&W, the FAA’s five-minute fire resistance mandate required Airbus to demonstrate that the tank’s aluminum-lithium alloy construction could withstand extreme temperatures without compromising evacuation timelines. Computational fluid dynamics (CFD) simulations and live fire tests were critical to validating these designs.

While different regulatory approaches between EASA and the FAA initially complicated the certification process, we should see both Pratt & Whitney GTF and CFM LEAP-1A engines A321XLR in the skies this year.
