Paris, Sept. 28 – Airbus shares dip after a quality flaw was identified in the best-selling A321neo jet, as the European planemaker confirmed an incorrectly applied anti-corrosion primer on fuselage stringers across a large batch of aircraft. The Airbus stock decline of more than one percent reflected investor concern that quality control gaps could complicate an already demanding aircraft delivery schedule for 2026. Industry sources traced the coating defect to a subcontractor serving Italian supplier Leonardo, marking another supply-chain test for the A321neo production system.
Airbus said flight safety is unaffected and that a repair has been defined, allowing airlines to keep taking delivery of A321neo jets, sometimes with maintenance concessions. The company reaffirmed its full-year guidance of around 870 aircraft deliveries after handing over 475 jets from January through August. External analysts noted that buyer reactions and the scale of repairs will determine whether the A321neo quality flaw delays the 870-unit target.
The latest A321neo coating issue follows an earlier fuselage-panel quality problem last December that contributed to missed 2025 deliveries. Airbus indicated the current defect is less severe, yet it again highlights pressure on quality controls as factories raise output from about sixty to seventy-five single-aisle aircraft a month. Leonardo confirmed TESI as one of several suppliers but did not specify work on the affected stringers.
The A321neo remains Airbus’s largest single-aisle jet and continues to outsell Boeing’s comparable 737 MAX variants, leaving European plants with a steep ramp-up after pandemic-era supply disruptions. Shares in the world’s largest planemaker lagged other CAC 40 blue-chip stocks on the news, keeping Airbus delivery progress and A321neo quality assurance under close market scrutiny through the remainder of the year.
