“查明原因”
用英语怎么说？

According to the aviation minister, ground controllers lost contact with the aircraft shortly after nine in the morning. Attempts to establish communication with the flight via radio proved abortive, and emergency crews were dispatched immediately once the crash was confirmed. The aircraft, identified as a twin-engine ATR-42, was capable of carrying up to fifty passengers. Authorities launched a comprehensive rescue operation in the challenging marshland environment, while crash investigators began gathering evidence to determine the cause of the disaster.

据航空部长称，地面管制人员在上午九点过后不久与该飞机失去了联系。通过无线电与该航班建立联系的努力徒劳无功，一旦确认坠机，应急队伍便立即被派出。该飞机被确认为一架双引擎ATR-42客机，最多可搭载五十名乘客。当局在条件恶劣的沼泽环境中展开了全面的营救行动，坠机调查人员也开始收集证据以查明原因。
