The Federal Aviation Administration has ordered fixes to the flight control computers on 39 U.S.-registered Airbus A330-941 airplanes, the type sold as the A330neo, after a landing in which all three primary computers faulted at once. In that event, the airplane lost its ground spoilers, thrust reversers and autobrake in the seconds after the wheels touched the runway.

The order, airworthiness directive 2026-22-02, was published in the Federal Register on October 27 and takes effect December 1, 2026. It requires operators to install a new flight control primary computer standard along with a set of companion modifications, and it contains no mention of an accident.
What failed on the runway
The Federal Register text describes the trigger as a triple “PRIM FAULT” at touchdown, a condition in which the three Flight Control Primary Computers on the airplane all report faults. The consequence listed in the directive is “loss of ground spoilers, thrust reversers, and autobrake,” three of the main systems that slow a jet after it lands.
The directive traces the root cause to an undue triggering of the rudder order “COM/MON” monitoring inside all three computers. In other words, a monitoring function meant to catch errors tripped when it should not have, and because the same logic ran in each of the three units, redundancy did not help.
The European regulator had already described the same occurrence. In EASA AD 2025-0208, issued September 24, 2025, the agency reported that the flight crew braked manually and stopped the aircraft without further incident. The FAA adopts that European directive rather than writing its own technical remedy.
Why 39 airplanes carry the FAA order
The FAA estimates that 39 airplanes of U.S. registry are affected. That figure counts only aircraft on the American register; the worldwide A330-941 fleet is larger, and those airplanes fall under EASA’s directive and the rules of other national authorities.
The order applies to the A330-941 alone. It does not reach the A330-200, A330-300 or A330-841, even though the family shares a name and a cockpit philosophy. Airbus’s older A330 variants use different flight control computer hardware and are outside the scope of this directive.
Under 14 CFR part 39, airworthiness directives are legally enforceable regulations. An operator that flies a covered airplane after the compliance date without the work done is out of compliance with federal rules, which is why the Federal Register notice matters even when the underlying fix has been available for a year.
Autobrake, spoilers and reversers are layered defenses. Spoilers dump lift so the wheels carry the weight of the airplane, the autobrake applies braking at a set rate, and the reversers redirect engine thrust forward. Losing all three together leaves pilots with manual wheel braking on a runway of unknown remaining length, which is the situation the FAA describes as possibly reducing control of the airplane.
The required fix and its cost
The directive requires installation of “a new FCPC standard and applicable concurrent modifications,” which the Federal Register notice breaks out as upgrades to the flight control primary computers, the flight management and guidance envelope computers, the flight warning computers and the electronic instrument system. It also adds a parts-installation restriction so that only a serviceable computer can be fitted.
The FAA puts the work at up to 23 work-hours at $85 an hour, or $1,955, plus up to $7,542 in parts. That is up to $9,497 per airplane and up to $370,383 across the U.S. fleet, a small figure against the cost of a grounded widebody.
Compliance times come from the European directive, which called for the computer upgrade to the P17B/M32NEO 2K2 standard within 12 months of its October 8, 2025 effective date. The FAA text does not set its own separate deadline. Operators of the 39 U.S. airplanes will therefore find that much of the required work is likely already scheduled or done, while the legal obligation under American rules begins December 1.
From the European directive to a U.S. final rule
The FAA first published the proposal on August 19, 2026, in a notice of proposed rulemaking under docket FAA-2026-8782. The agency received one comment on the docket, from the Air Line Pilots Association, International, which supported the proposal without change.
The final rule was adopted as proposed, with only minor editorial changes. Lona C. Saccomando, Acting Deputy Director of the FAA’s Integrated Certificate Management Division, signed it, and Aviation Safety Engineer Frank Carreras is listed as the contact for technical questions.
One question the notice leaves open is how many airplanes outside the U.S. had already received the new computer standard by the time the American order was finalized. The FAA counts only the U.S. register, and the European directive lists affected aircraft by manufacturer serial number, from MSN 1819 to MSN 2088, without a published tally of completed work.
