Taipei: All Taiwanese airlines completed the required software restoration on Airbus A320-series aircraft before 7 a.m. Sunday, following an emergency directive issued after a technical failure in the United States, Taiwan's Civil Aviation Administration (CAA) said.

According to Focus Taiwan, Airbus announced on Friday that around 6,000 A320-family jets worldwide must undergo software updates and may not be operated without the fix. The announcement followed reports of a flight-control system malfunction linked to solar flare interference.

The CAA reported that it received the European Union Aviation Safety Agency's (EASA) emergency airworthiness directive on Saturday and immediately instructed local airlines to carry out inspections and the necessary software updates before the order took effect at 8 a.m. Sunday.

The CAA confirmed that all in-service A320-family aircraft operated by Taiwanese carriers had completed the required updates before the deadline.

Only Tigerair Taiwan reported minor delays due to the adjustments, while all other airlines operated normally.
