Imagine this: You're soaring through the sky, enjoying a smooth flight, when suddenly, your plane inexplicably dives! This is the unsettling reality airlines are facing, as Airbus has issued a critical warning about a potential threat to A320 family aircraft: solar flares.
Airbus has alerted airlines operating A320s about the risk of flight control software corruption due to intense solar radiation. This isn't just a hypothetical concern; it's a real-world issue. A recent incident involving a JetBlue Airways A320 on October 30th, which resulted in a sudden altitude drop and an emergency landing in Florida, serves as a stark reminder of the potential consequences. At least 15 people were injured in the incident.
But here's where it gets controversial... An Alert Operators Transmission (AOT) reviewed by The Air Current, instructs airlines to take immediate action. They must address the issue before their next flight or risk being grounded by an upcoming European Union Aviation Safety Agency (EASA) emergency airworthiness directive, expected on November 28th. The scope of this issue is vast, affecting both older A320ceo and current-generation A320neo family aircraft. Considering the A320 is the most-flown commercial aircraft globally, this advisory impacts potentially thousands of planes.
Airlines worldwide have been notified, with two senior airline leaders confirming the urgency of the situation. The AOT details the specific vulnerability: "An Airbus A320 aircraft recently experienced an uncommanded and limited pitch down event. The autopilot remained engaged throughout the event, with a brief and limited loss of altitude, and the rest of the flight was uneventful." The investigation revealed a vulnerability in the ELAC B hardware fitted with software L104 when exposed to solar flares. The advisory warns that in the worst-case scenario, this could lead to an uncommanded elevator movement, potentially exceeding the aircraft's structural limits.
The solution? Airlines must either revert to an earlier software version or replace the affected elevator aileron computer (ELAC) hardware with one containing the older software. Airbus estimates this maintenance action will take approximately three hours. An Airbus spokeswoman emphasized that they are proactively working with airlines and regulators to address the issue before the expected emergency airworthiness directive.
This warning comes at a particularly inopportune time, coinciding with one of the busiest holiday travel periods in the United States, which could lead to widespread disruptions. Airbus acknowledges these recommendations will cause operational disruptions and has apologized for the inconvenience, vowing to work closely with operators while prioritizing safety.
