Airbus advises operators to prepare horizontal stabilizer checks on A330neo

Airbus is recommending that selected A330neo operators anticipate horizontal stabilizer inspections during upcoming scheduled maintenance visits. This preventive measure follows the discovery of a manufacturing quality issue on an assembly-line airframe, where a tool was reportedly left inside the structure.

The manufacturer is currently defining the final inspection intervals and the affected airframe population in coordination with EASA, with definitive guidelines expected by mid-November. According to Airbus, EASA has established that the issue presents no immediate safety hazard, and no grounding or immediate fleet-wide action has been mandated.

The manufacturing anomaly previously disrupted supply chains, halting A330neo deliveries across June and July, with only a single delivery recorded in August. Components manufactured across facilities in Illescas, Cádiz, and assembled in Getafe before transit to Toulouse have since undergone revised assembly controls. Aircraft on the assembly line were cleared for customer handover after comprehensive reviews.

Preliminary estimates indicate that A330neo units delivered between January 2021 and July 2026 could ultimately fall within the inspection envelope. However, ongoing reviews of manufacturing records by Airbus and EASA could reduce that total. To date, no foreign object debris or structural defects have been identified across aircraft currently in commercial service.
