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 affected Airbus A320 aircraft due to flight control software vulnerabilities influenced by strong solar radiation, impacting approximately 6,000 aircraft [1][4]. Group 1: Emergency Airworthiness Directive - EASA's directive was prompted by Airbus reporting that a significant number of A320 series aircraft were affected by flight control software issues, necessitating urgent maintenance [1][4]. - Airbus indicated that the affected aircraft would require immediate software and/or hardware protective measures to ensure flight safety [1][4]. Group 2: Technical Assessment and Incident Background - The directive followed an incident on October 30 involving a JetBlue A320-200 that experienced an uncommanded and limited descent, leading to injuries onboard, with preliminary investigations pointing to software issues [6][4]. - Airbus's initial technical assessment identified a fault in the ELAC system as a potential contributing factor, which, if uncorrected, could lead to uncommanded control surface movements [4][6]. Group 3: Impact on Airlines - As of the end of November, there were 2,015 A320 aircraft in China, representing 48.3% of the total civil aviation fleet, distributed across 24 airlines [6][7]. - Industry experts suggest that while there will be some impact on operations, the majority of aircraft can be resolved through software updates, with minimal downtime expected [7].
