Thursday, 04 March 2021_Boeing Co. has raised concerns over the design of arch-rival Airbus’ newest narrow-body jet, the A321XLR, saying a novel type of fuel tank could pose fire risks.

Boeing cites risks in design of newest Airbus jetThe US plane giant’s intervention is not without precedent in a global system that regularly allows manufacturers to chime in whenever safety rules are being interpreted in a way that might affect the rest of the industry.

But it comes at a pivotal moment as Boeing emerges from a two-year safety crisis over its competing 737 MAX, and Airbus faces its own crucial test of the tougher mood expected from regulators worldwide following the MAX’s 20-month grounding.

In a submission to the European Union Aviation Safety Agency (EASA), Boeing said the architecture of a fuel tank intended to increase the A321XLR’s range “presents many potential hazards.”

The debate surrounds the hot-selling A321XLR’s main marketing point - the longest range of any single-aisle jet.

In most jets, fuel is carried in wings and central tanks.

To meet demand for longer routes, Airbus has already added optional extra fuel tanks inside the cargo bay of some A321s.

For the A321XLR, Airbus plans to eke out more space for fuel by moulding one tank directly into the fuselage, meaning its shape would follow the contours of the jet and carry more fuel.

The concept caught the attention of EASA which in January said it would impose special conditions to keep passengers safe.

“An integral fuselage fuel tank exposed to an external fire, if not adequately protected, may not provide enough time for the passengers to safely evacuate the aircraft,” it said.

In comments to EASA first reported by Flightglobal, Boeing cited risks if a jet veers off a runway or its wheels fail.

“Public consultation is part-and-parcel of an aircraft development programme,” an Airbus spokesman said, adding any issues raised would be tackled together with regulators.
