Key Points

  • Airbus located a production quality issue on the horizontal tail plane of an A330 before delivery.
  • The issue caused a slowdown in A330 deliveries over the summer, but Airbus says deliveries have resumed.
  • Airbus confirmed the problem following Bloomberg's report and said it has identified the root cause.

Summary: Airbus has reported an isolated production quality issue affecting the horizontal tail plane of an A330 jet, discovered before delivery. The defect contributed to a slowdown in A330 deliveries over the summer. Airbus confirmed the issue after it was initially reported by Bloomberg, said it has identified the root cause, and indicated that deliveries have resumed following the summer disruption.

Airbus, the European planemaker, said on Thursday that it found a quality problem on an A330 aircraft during pre-delivery checks. The problem related specifically to the horizontal tail plane and was identified before the aircraft was handed over to its customer.

The company confirmed the existence of the issue after Bloomberg first reported the matter. Airbus further stated that it has located the root cause behind the defect. While the problem led to a slowdown in A330 deliveries during the summer period, Airbus said deliveries have since restarted following that temporary reduction in pace.

The company framed the incident as an isolated quality issue located on the horizontal tail plane of a single A330 jet, and highlighted that investigations led to an identified root cause. The timing of discovery - prior to delivery - meant the defect was addressed before the aircraft entered service.

Key operational details released by Airbus are limited to confirmation of the defect, the identification of its root cause, and the fact that deliveries, which slowed in the summer, have resumed. The firm made these statements on Thursday, reiterating that the issue was isolated and that shipment activity for the A330 has returned to normal following the summer slowdown.

Given the narrow set of facts released, broader effects beyond the specific slowdown are not detailed in Airbus's statement. The company did not provide additional figures, timelines, or further technical specifics in its public comments accompanying the initial confirmation and root-cause finding.
