Airbus A330neo deliveries nearly came to a halt for three months after the manufacturer identified a quality issue affecting the aircraft’s horizontal tail plane, disrupting handovers after the program had been delivering aircraft at close to its current production rate.
Airbus confirmed the issue to Bloomberg, saying additional inspections were required during production. The manufacturer described the problem as isolated and said its root cause had been identified.
“The root cause is identified and A330 deliveries have resumed,” Airbus told the outlet.
The impact is visible in delivery figures. Airbus handed over three A330neos in March, two in April and four in May, for a total of nine aircraft in three months.

No A330neos were delivered in June or July. The interruption ended on August 11, when Starlux Airlines received an A330-900, MSN 2133. It was the only aircraft of the family handed over during August, according to Bloomberg.
Airbus therefore delivered just one A330neo between June and August, compared with nine in the previous three months.
The figures do not mean production stopped. Airbus said the additional inspections slowed handovers during the manufacturing process, which could leave aircraft awaiting checks or corrective work before delivery.
Horizontal tail plane issue
Airbus has not disclosed the precise nature of the quality problem or how many aircraft required inspection. There is also no indication that the issue requires action on A330neos already operating with airlines.
The horizontal tail plane, or horizontal stabilizer, provides longitudinal stability and carries the elevators used to control aircraft pitch.
Airbus said deliveries have now resumed, although it has not disclosed how many aircraft were affected or how quickly the accumulated aircraft can be handed over.
Almost 400 A330neos remain in backlog
The disruption comes as the A330neo carries its largest backlog since the program was launched.
Airbus data through July showed 523 firm orders for the two variants and 126 deliveries. The A330-900 accounts for almost all of them, with 511 orders and 118 deliveries through July. The Starlux aircraft delivered in August raised that figure to 119.
That leaves approximately 392 A330-900s still to be delivered. The smaller A330-800 has accumulated only 12 orders, with eight aircraft delivered.
Combined, the two variants have approximately 396 aircraft remaining in backlog, or around three quarters of all A330neos ordered.
Airbus currently builds about four A330s per month and plans to increase production to five per month in 2029. Monthly production and delivery figures do not necessarily match, but the nine handovers between March and May show how sharply the delivery flow changed after the quality problem emerged.
The interruption comes during a period of renewed commercial demand for the A330neo, particularly the A330-900, as airlines replace older widebodies and seek an alternative to the Boeing 787 and larger Airbus A350.
It also adds another constraint as Airbus seeks to meet its overall 2026 delivery target. The manufacturer expects to hand over about 870 commercial aircraft this year, within a range of 850 to 890, while dealing with engine and other supply-chain constraints across its aircraft programs.
