Airbus A320s Could Be Temporarily Grounded Worldwide for Software Update — After Faulty JetBlue Computer Triggered Sudden Uncommanded Descent by Gary Leff on November 28, 2025 According to aviation insiders, there’s a possible grounding of Airbus narrowbodies coming worldwide. Watchdog JonNYC was first to share this information. However I do not expect aircraft to be grounded for long, and I’d expect a staggering to minimize flight disruptions. also 100%++ unconfirmed "someone says AA Will be doing cxl package for A320 fleet … but this will effect ALL a320 worldwide ",mandatory software update" — JonNYC (@xJonNYC) November 28, 2025 All signs say this A320 issue is accurate, airworthiness directive from Airbus imminent Unconfirmed — JonNYC (@xJonNYC) November 28, 2025 Jon suggests that the issue is an with an aileron computer. This was identified as the cause of a JetBlue A320 issue on October 30th where a Cancun to Newark flight “unexpectedly pitched downward without pilot input” and diverted to Tampa. The Thales ELAC 2 computer malfunctioned and was replaced. This interpets pilot commands to control the aircraft. 10-15 passengers were hospitalized after the aircraft rapidly descended without being instructed by pilots to do so. The uncontrolled descent “likely occurred during an ELAC switch change” according to the National Transportation Safety Board. This is not supposed to happen! If there’s an issue with one ELAC computer, the other is supposed to take control without missing a beat. Presumably, then, what’s being anticipated is a requirement related to these computers. Each aircraft has two, supplied primarily by Thales. There’s also a repair and overhaul ecosystem, not just new equipment production. The U.S. FAA proposed an airworthiness directive in 2018 requiring all ELAC units on Airbus A320 family aircraft to be upgraded with new software or replaced with upgraded units due to angle of attack issues. With about 10,000 A320-family aircraft in service (all ...
