Airbus has rapidly completed a software update for nearly 6,000 Airbus A320 family aircraft, resolving a critical computer issue caused by a faulty software update. The problem, linked to a malfunction in the dual ELAC flight control computers from Thales, led to safety concerns after an incident involving an unintentional altitude loss during a flight by JetBlue on October 30, which resulted in injuries among passengers. The European Aviation Safety Agency (EASA) ordered airlines to revert to a previous, safe software version, which most airlines implemented swiftly, causing only minor disruptions and short-term aircraft grounding. Only fewer than 100 aircraft require hardware replacements due to persistent computer malfunctions. The root cause was attributed to solar particle streams affecting onboard data processing. Following the update, most aircraft are back in service, and flight operations have largely normalized, with some airlines experiencing minimal delays. The incident caused a temporary decline in Airbus's stock price, which fell by up to 10% amid concerns over the software issues. Airbus’s CEO Guillaume Faury apologized for the logistical challenges and delays caused by the problem. The quick resolution has prevented widespread flight cancellations, although some disruptions remain, especially in the US and Japan, where several flights were canceled or delayed.
