Airbus on Friday urged operators to immediately install software updates to A320 family aircraft after finding a potential flight-control vulnerability. The decision follows analysis of an October 30 incident involving JetBlue Flight 1230, which experienced a sudden altitude loss en route from Cancún to Newark and caused several injuries. Airbus said intense solar radiation can corrupt data critical to flight-control functioning, creating the risk identified in the investigation.
Airbus has coordinated with aviation authorities and issued an Alert Operators Transmission so airlines can apply available software and hardware protections. The manufacturer said a significant number of in-service A320s may require the protections. The European Union Aviation Safety Agency ordered an immediate software change for a set of A320s, and the FAA was expected to issue a similar emergency airworthiness directive; NPR contacted the FAA but had not received a response.
The A320 family is the world’s most-used commercial aircraft, with more than 9,000 examples in service globally and about 1,600 in the United States, according to aviation analytics firm Cirium. Airbus warned the mandated updates could cause operational disruptions, a concern as the directive arrived during a busy holiday travel weekend.
Airline responses:
– American Airlines said it acted quickly; as of 6 p.m. CT fewer than 150 of its A320-series aircraft still needed the update, with completion expected Friday and Saturday and some delays anticipated while minimizing cancellations.
– Delta Air Lines said it expects any operational impact to be limited.
– United Airlines initially reported no fleet-wide effect but later identified six affected aircraft and expected only minor disruption to a few flights.
– Frontier said it was evaluating Airbus’s notice.
– Allegiant said it is working to minimize delays and will contact affected passengers directly.
– JetBlue said it has begun work on affected aircraft and is seeking to limit disruptions.
– NPR reached out to Spirit Airlines but had not received a response.
Airbus emphasized that safety is the overriding priority while airlines implement the protections. Report contributed by NPR’s Joel Rose.
