Airbus has identified a quality issue affecting around 500 A321neo aircraft, with no risk to passenger safety

Airbus has identified a quality issue affecting the fuselage structure of some A321neo aircraft, the European aerospace group announced on Thursday. The defect affects approximately 500 aircraft, nearly 250 of which are already in service, while another 250 are in production. The company said the situation is under control and poses no risk to flight safety.

The problem consists of a “deviation” in the protective coating applied to certain longitudinal components of the fuselage framework. Airbus said a remedy is available, but inspections and repairs could cause delays in aircraft deliveries.

The A321neo is the largest and most popular single-aisle aircraft produced by Airbus. The aircraft can carry up to 244 passengers and has a range of approximately 7,200 kilometers.

The incident marks the second problem recently reported involving the fuselage of this model, after Airbus flagged nonconformities in fuselage panels in December. The announcement comes as the company is seeking to increase production of single-aisle aircraft from approximately 60 to 75 units per month.

European regulators could issue a directive requiring the defects to be repaired within a specified timeframe. Delta, an A321neo operator, said it is in contact with the manufacturers and will comply with official recommendations and requirements.
