Nice thank you, this one has the details I was curious about
In a service difficulty report submitted to the FAA the operator stated, that the Elevator Aileron Computer #2 (ELAC2) was identified faulty causing an uncommanded pitch down in cruise flight, the autopilot remained engaged
On Nov 7th 2025 the NTSB reported: "During cruise, the aircraft experienced an uncontrolled descent for approximately 4-5 seconds before the autopilot corrected the trajectory. This likely occurred during an ELAC switch change." The occurrence caused 10 injuries on board, the NTSB opened an investigation.
The subsequent investigation identified a vulnerability with the ELAC B hardware fitted with software L104 in case of exposure to solar flares.
This identified vulnerability could lead in the worst case scenario to an uncommanded elevator movement that may result in exceeding the aircraft structural capability.
