在亚利桑那州发生致命的2月坠机事件和前三起事故后,国家航空安全委员会敦促立即检查1 883名Bombardier Learjets的起落架风险,该风险与不当获取的扣留螺栓有关。 The NTSB has urged immediate inspection of 1,883 Bombardier Learjets over a landing gear risk tied to improperly secured retaining bolts, following a fatal February crash in Arizona and three prior incidents. 董事会说,尽管有2022年的《服务公告》,但只有12%的受影响飞机受到检查,它迫使民航局要求遵守规定,并在维护后要求进行目视检查。 The board says only 12% of affected planes have been checked despite a 2022 service bulletin, and it is pushing the FAA to mandate compliance and require visual checks after maintenance. 庞巴迪支持一项授权，但美国联邦航空局尚未发布适航指令。 Bombardier supports a mandate, but the FAA has not issued an airworthiness directive.
