香港货机偏离跑道致两死事故公布调查进展：第4发动机推力杆前移致飞机左偏 暂未发现机件故障
香港民航意外调查机构10月13日就2025年10月20日香港国际机场货机偏离跑道事故发表调查临时声明。涉事飞机为土耳其ACT航空公司一架波音747-481BDSF型货机（登记标志TC-ACF），代表阿联酋航空货运公司经营，当日凌晨自迪拜抵港，着陆滑行期间向左偏转并偏离跑道，撞及一辆停放在跑道范围外的机场保安巡逻车辆后冲入海中，车上两名机场保安人员死亡。
调查小组表示，已完成主要调查工作，包括回收飞机残骸，收集航空公司、气象服务、航空交通管制及机场等相关数据和记录，会见涉事机组人员，收集航班文件、飞行数据及驾驶舱录音等证据，并将飞机部件送往制造国检验，调查人员亦曾前往海外监督重要检验工作。
临时声明指出，调查发现涉事货机的第4号发动机推力杆向前移动，导致飞机在着陆滑行过程中向左偏转并偏离跑道；截至目前，相关飞机部件的技术检验并未发现与意外相关的机件故障。
调查仍在进行中，重点之一是确定第4号发动机推力杆的推进是由机械驱动还是受到外力所致，工作包括进行专家声谱分析；调查小组亦会安排飞行模拟试验，重组当日飞机偏离跑道的情况，并检视同型号飞机的意外历史。调查机构已于2025年11月18日发表调查初步报告，并以2026年年底前完成所有调查工作为目标，最终报告将在所有调查工作及法定审阅程序完成后公布。
运输及物流局对临时声明表示高度关注，已要求民航意外调查机构在确保调查严谨专业的前提下全力推进。涉事货机登记地为土耳其，运输及物流局一直与土耳其驻香港总领事馆保持紧密沟通，就事故后续及调查协调工作互通信息，土耳其方面亦一直全力配合与协助。民航意外调查机构发言人表示，调查涉及复杂的技术流程，需要与多方核实资料；该机构根据《香港民航（意外调查）规例》及国际民用航空组织的标准进行调查，目的是找出事故原因、审视人为因素，并提出安全建议。
Hong Kong Releases Interim Findings on Fatal Cargo Plane Excursion: No. 4 Engine Thrust Lever Moved Forward, No Mechanical Fault Found So Far
Hong Kong's Air Accident Investigation Authority (AAIA) on October 13 issued an interim statement on the October 20, 2025 runway excursion involving a Boeing 747-481BDSF freighter (registration TC-ACF) operated by Turkey-based ACT Airlines on behalf of Emirates SkyCargo. The aircraft, arriving from Dubai in the early hours, veered left during its landing roll at Hong Kong International Airport, departed the runway and plunged into the sea after striking an airport security patrol vehicle parked outside the runway area, killing the two security staff members on board.
The investigation team said the main investigation work has been completed, including recovery of the wreckage; collection of data and records from the airline, meteorological services, air traffic control and the airport; interviews with the flight crew; and collection of flight documents, flight data and cockpit voice recordings. Aircraft components were sent to the country of manufacture for examination, and investigators travelled overseas to oversee key inspections.
According to the interim statement, the investigation found that the No. 4 engine thrust lever of the freighter moved forward, causing the aircraft to veer left during the landing roll and depart the runway. Technical examinations of the relevant components conducted so far have found no mechanical fault related to the accident.
The investigation is continuing. One focus is determining, through expert acoustic analysis, whether the thrust lever movement was mechanically driven or caused by an external force. The team will also conduct flight simulation trials to reconstruct the excursion and review the accident history of the same aircraft type. A preliminary report was published on November 18, 2025, and the authority aims to complete all investigation work by the end of 2026, with the final report to be released after the investigation and statutory review procedures are completed. The Transport and Logistics Bureau said it attached great importance to the interim statement and had asked the AAIA to press ahead in a rigorous and professional manner. As the aircraft was registered in Turkey, the bureau has maintained close communication with the Turkish Consulate-General in Hong Kong on follow-up and investigation coordination, and the Turkish side has been fully cooperating. An AAIA spokesperson said the investigation involves complex technical processes requiring verification with multiple parties; the authority conducts investigations under the Hong Kong Civil Aviation (Investigation of Accidents) Regulations and International Civil Aviation Organization standards, with the aim of identifying causes, examining human factors and making safety recommendations.
