EASA Issues Emergency Directive for Software Update on A320 Aircraft

EASA Issues Emergency Directive for Software Update on Airbus A320 Aircraft
The European Union Aviation Safety Agency (EASA) has issued an Emergency Airworthiness Directive (AD) mandating an urgent software update for Airbus A320 Family aircraft following the discovery of a critical flight control vulnerability. The directive, effective from 23:59 UTC on November 29, 2025, was prompted by a recent incident involving an A320 that experienced an uncommanded and limited pitch-down event. This sudden altitude drop forced a diversion and resulted in hospitalizations among JetBlue passengers.
Flight Control Vulnerability and Investigation
Airbus’s investigation revealed that intense solar radiation can corrupt data essential to the operation of the aircraft’s flight controls, specifically affecting the Elevator Aileron Computer (ELAC). The component identified as ELAC B L104 was implicated as a potential cause of the incident. EASA has warned that if this issue remains unaddressed, it could lead to uncommanded elevator movements, which might exceed the aircraft’s structural limits and compromise safety.
In response, Airbus issued an Alert Operators Transmission (AOT) to inform operators of the risk, particularly given the current increase in solar flare activity. EASA’s directive requires airlines to replace or modify all affected ELAC units with a serviceable version, ELAC B L103+, following Airbus’s detailed instructions. In certain cases, hardware protection measures must be installed prior to applying the software update. The directive also prohibits the installation of the affected ELAC on any aircraft going forward.
Operational Impact and Industry Response
The directive affects more than 11,000 A320 Family aircraft globally, with a significant number identified as potentially vulnerable. Major airlines, including American Airlines, have reported operational delays as they work to comply with the mandated updates. The timing of the directive, coinciding with the busy travel period following the US Thanksgiving holiday, has raised concerns about widespread flight disruptions.
EASA requires that the ELAC replacement or modification be completed before the next flight after the directive’s effective date. A limited ferry flight allowance—up to three flight cycles, non-ETOPS, and without passengers—is permitted solely to reposition aircraft for maintenance purposes.
Airbus, which collaborated closely with EASA in issuing the advisory, acknowledged the operational challenges posed by the directive. The manufacturer emphasized that safety remains the overriding priority and expressed regret for the inconvenience caused to operators and passengers.
The UK Civil Aviation Authority has confirmed that some A320 Family aircraft registered to UK airlines are also affected. The authority noted that affected airlines may need to ground aircraft or perform software changes in the days following the directive’s implementation.
As airlines worldwide prioritize compliance, the aviation sector is preparing for schedule adjustments and potential delays, underscoring the critical importance of immediate action to ensure passenger safety.
