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].

Core Viewpoint - Airbus has announced an urgent grounding of a significant number of A320 aircraft due to flight control software vulnerabilities affected by strong solar radiation, impacting approximately 6,000 aircraft that will require immediate repairs [1][2]. Group 1: Impact on Aircraft Operations - The grounding is a response to an incident involving a JetBlue A320 that experienced a sudden altitude drop, injuring several passengers, which prompted Airbus to analyze the situation and issue a stop-flight order to all operators using the affected software [2]. - Over half of the global A320 fleet is affected, leading to numerous flight cancellations and delays across various airlines [3]. - American Airlines, the largest operator of A320 aircraft, reported that around 340 of its 480 A320s require repairs, with most expected to be completed by November 29 [3]. Group 2: Repair and Maintenance Challenges - The repair process involves reverting to an earlier software version, which is relatively simple; however, the aircraft must be transferred to maintenance centers, causing delays in returning to service [2]. - Approximately 1,000 aircraft will also require hardware replacements, with operations expected to take several weeks [2]. - Airlines such as Avianca have indicated that over 70% of their fleet is affected, leading to significant disruptions and the suspension of ticket sales for flights before December 8 [3][4]. Group 3: Broader Industry Implications - Other airlines, including Lufthansa, easyJet, Jetstar, Air New Zealand, and ANA, are also planning to ground aircraft for short-term repairs [4]. - The current peak travel season, combined with a backlog of aircraft awaiting engine repairs and a shortage of skilled technicians, may exacerbate the situation, potentially leading to widespread flight disruptions [4].

Core Viewpoint - The European Union Aviation Safety Agency (EASA) issued an emergency airworthiness directive requiring the immediate grounding of all affected Airbus A320 aircraft due to concerns over flight control software vulnerability to strong solar radiation [1][4]. Summary by Sections 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 that could be compromised by intense solar radiation, necessitating urgent grounding and implementation of existing software and/or hardware protective measures to ensure fleet safety [1][4]. Technical Assessment and Background - A recent incident involving a JetBlue A320-200 aircraft, which experienced an uncommanded and limited dive, raised alarms. The automatic pilot remained engaged during the event, leading to a brief altitude loss before normal flight resumed. Initial technical assessments by Airbus indicated that a fault in the Elevator and Aileron Control (ELAC) system could be a contributing factor [4][6]. - Airbus confirmed that the A320 aircraft requires urgent replacement of a flight control software susceptible to solar radiation, which could damage critical data necessary for flight control. Airbus proactively contacted aviation authorities to implement preventive measures [4][6]. Impact on Airlines - Reports suggested that Airbus would recall over 6,000 A320 aircraft globally. However, Airbus China clarified that this statement was inaccurate, as the software update could be performed locally without sending the aircraft back to Airbus headquarters in France [1][6]. - As of the end of November 2025, China has a total of 2,015 A320 aircraft, representing 48.3% of the total civil aviation fleet, distributed among 24 airlines [6][7]. - Industry experts indicated that while there would be some impact on operations, the majority of aircraft could resolve the issue through software updates, with minimal aircraft requiring software replacement. The software upgrade process is estimated to take about two hours [7].

此外，美国航空公司当日表示，由于大量空客A320飞机需要进行重大软件升级，预计将出现一些运营延误。 澳大利亚捷星航空、新西兰航空公司、日本全日空航空、哥伦比亚航空公司也宣布，由于空中客车公司对全球超 过6000架A320系列客机实施紧急维修，部分由A320机型执飞的航班已被迫停飞。 当地时间28日。空中客车公司一名发言人表示，约6000架空客A320飞机需要紧急更换一种易受太阳辐射影响 的飞行控制软件。此前，10月底美国捷蓝航空的一架飞机发生一起事故，促使空客采取行动。空客表示，在对该 技术事故进行分析后，于28日通知所有使用该软件的客户"立即停止飞行"。 分析结果显示，"强烈的太阳辐射可能会损坏飞行控制所需的关键数据"。这一结论已由空客方面确认。 空客A320飞机（资料图） ...
