全球约6000架A320飞机需紧急停飞，空客最新回应

Core Viewpoint - The European Union Aviation Safety Agency (EASA) issued an emergency airworthiness directive on November 28, requiring the immediate grounding of all Airbus A320 aircraft due to flight control software vulnerabilities affected by strong solar radiation, impacting approximately 6,000 aircraft that will undergo urgent repairs [1][5]. Group 1: Emergency Airworthiness Directive - EASA mandated the grounding of multiple A320 aircraft following a report from Airbus about flight control software being susceptible to strong solar radiation, necessitating urgent maintenance [1][4]. - Airbus indicated that around 6,000 A320 aircraft are affected and will require urgent repairs, although Airbus China clarified that only local software adjustments are needed, not a recall to France [1][7]. Group 2: Incident Background - The emergency directive was prompted by an incident on October 30 involving a JetBlue A320-200 that experienced an uncontrolled descent, resulting in injuries. The investigation pointed to software issues as the cause [7]. - Airbus's preliminary technical assessment identified a fault in the ELAC system as a potential contributing factor, which, if uncorrected, could lead to unintended control movements exceeding the aircraft's structural limits [4][5]. Group 3: Impact on Chinese Airlines - As of the end of November, China has 2,015 A320 aircraft, accounting for 48.3% of the total civil aviation fleet, distributed among 24 airlines [7]. - Industry experts suggest that while there will be some impact on operations, the majority of aircraft can resolve the issue through software updates, with minimal downtime required for the process [8].
