Airbus Resolves Software Glitch Affecting Majority of Jets

Airbus Resolves Software Glitch Affecting Majority of Jets
Airbus has successfully addressed a significant software glitch impacting the majority of its A320 family aircraft. Nearly 6,000 jets have now been updated, with fewer than 100 still awaiting the necessary software fix. The rapid response from Airbus and global airlines helped mitigate major disruptions to flight schedules, despite the issue arising during the peak holiday travel season.
Nature of the Glitch and Response
The technical fault was uncovered following an incident that revealed intense solar radiation could corrupt data essential to flight control systems. In response, Airbus mandated immediate software repairs for more than half of its worldwide A320 fleet. Airlines worldwide mobilized quickly to implement the updates, a challenging task given the timing coincided with the busy Thanksgiving weekend in the United States, a critical period for carriers such as Delta, United, and American Airlines.
Airbus described this recall as the largest in its 55-year history. The corrective measure involved installing an older, more stable version of the software, a process that takes approximately two to three hours per aircraft. By December 1, 2025, the vast majority of the affected 6,000 jets had received the update, with fewer than 100 still pending the patch before returning to service. Deutsche Bank analysts estimate that up to 15% of these aircraft may also require a hardware upgrade to fully resolve the issue.
In an official statement, Airbus expressed regret for any inconvenience caused to passengers and airlines, acknowledging the challenges posed by the event.
Additional Quality Concerns and Market Impact
Despite the swift resolution of the software problem, Airbus shares declined by as much as 6% following reports of a separate quality issue involving a “limited number” of A320 metal fuselage panels. Airbus confirmed it is adopting a cautious approach by inspecting all potentially affected aircraft, although only a subset is expected to require further remedial action. The company stated that the root cause of the panel defect has been identified and contained, and assured that all newly manufactured panels comply with stringent quality standards.
The software vulnerability, linked to solar flare exposure, triggered a coordinated global effort to safeguard the A320 fleet. Thanks to the prompt and collaborative response from Airbus and its airline partners, operational disruptions were minimized, and most aircraft have since returned to service.
This incident comes shortly after the A320 surpassed Boeing’s 737 as the world’s most-delivered jet, highlighting the critical importance of maintaining safety and reliability across Airbus’s extensive fleet.
