Airbus shares fell by more than 10% during intraday trading

Shares of Airbus Group fell by more than 10 percent during intraday trading on Monday before narrowing their losses later in the session on the Paris stock exchange.

The decline came after Airbus confirmed that a significant number of A320-series aircraft required immediate precautionary action due to flight-control software vulnerabilities that could be affected by intense solar radiation.

In its Monday statement, Airbus said that the vast majority of the roughly 6,000 aircraft delivered worldwide have now received the necessary software modifications. Fewer than 100 aircraft are still undergoing updates.

Airbus told Xinhua that as of Sunday, all A320-series aircraft in China's civil aviation fleet requiring preventive measures had completed the necessary software fix in accordance with airworthiness directives and Airbus technical documentation. Normal operations of China's A320 fleet will not be affected.

Airbus again apologized for the challenges and delays caused to passengers and airlines and reiterated that safety remains its top priority.
