I. Core Content Overview

This document is the Malaysia Airlines Boeing B777-200ER (9M-MRO) Safety Investigation Report issued by the Malaysian ICAO Annex 13 Safety Investigation Team on 02 July 2018. It provides a comprehensive analysis of the disappearance of Malaysia Airlines Flight MH370 on 08 March 2014, covering factual information, technical details, and safety recommendations.

II. Main Sections and Key Information

1. Factual Information (Pages 1-273)

• Flight History: MH370 departed from Kuala Lumpur, en route to Beijing. The flight deviated from its filed route and was last seen on radar.
• Radar and Communication Data:
  • The aircraft was detected by Malaysian military radar and DCA civilian radar from Kota Bharu.
  • The last radio communication occurred at 08:11, and no distress signals were received.
• Search Operations:
  • A large-scale search was initiated after the aircraft went off radar.
  • Debris was found in the Indian Ocean, primarily in the Southern Hemisphere.
• Injuries and Aircraft Damage:
  • No injuries to persons were reported.
  • The aircraft was damaged beyond recognition, with significant debris found.
• Crew and Passenger Details:
  • Crew profiles, including the Pilot-in-Command (PIC) and First Officer (FO), were reviewed.
  • There were no reports of injuries or casualties.
• Cargo and Dangerous Goods:
  • A lithium-ion battery and mangosteen fruits were among the items on board.
  • The report discusses the potential risks of these items in the cargo hold.
• Aircraft Systems:
  • Detailed descriptions of airframe, engines, electrical systems, and communications were included.
  • Airworthiness and maintenance records were examined, including deferred defects and technical logs.

2. Analysis (Pages 275-428)

• Diversion from Flight Plan:
  • The aircraft deviated from its planned route, and simulator sessions were conducted to reenact the flight path.
  • The diversion was not detected by standard procedures, and the role of air traffic services was analyzed.
• Air Traffic Services (ATS) Operations:
  • The ATS procedures were reviewed, including communication between air traffic control centers.
  • The responsibilities of air traffic controllers and duty shift systems were evaluated.
• Human Factors and Medical Issues:
  • The health and behavior of the flight crew were examined, including psychological and social events.
  • Voice recognition of radio transmissions was conducted to assess crew behavior.
• Satellite Communications (SATCOM):
  • SATCOM ground station logs were analyzed for the 1825 and 0019 log-on events.
  • Possible reasons for communication loss were explored, including Doppler effect.
• Wreckage and Impact Analysis:
  • Debris was examined for damage and origin.
  • Marine life examination was conducted to determine if the debris had been in the ocean for a long time.
• Organizational and Management Issues:
  • The Department of Civil Aviation (DCA) and Malaysia Airlines were evaluated for their safety management systems and operations procedures.
  • Crew training, flight operations, and air traffic control coordination were assessed.

III. Findings and Conclusion (Pages 429-443)

• Findings:
  • The flight path deviation was not explained by known technical or human factors.
  • No distress signals were transmitted.
  • The crew profiles did not indicate any immediate medical or psychological issues.
  • Aircraft systems were found to be in good condition, with no evidence of mechanical failure.
• Conclusion:
  • The exact cause of the disappearance remains unknown.
  • The search efforts were extensive but did not locate the wreckage.
  • The data from radar and communications is incomplete, making a definitive conclusion difficult.

IV. Safety Recommendations (Pages 444-448)

• Department of Civil Aviation (DCA):
  • Improve ATS procedures and communication protocols.
  • Enhance coordination between air traffic control centers.
• Civil Aviation Authority of Vietnam (CAAV):
  • Review ATS procedures for cross-border operations.
• Malaysia Airlines:
  • Strengthen crew training and management.
  • Improve flight operations and safety management systems.
  • Enhance cargo handling and monitoring.
• Malaysia Airports Holdings Berhad:
  • Review ground handling procedures.
• International Civil Aviation Organization (ICAO):
  • Update guidelines on aircraft tracking and communication systems.

V. Appendices (Pages 449 onwards)

• The report includes 15 appendices, covering:
  • Letters of agreement between DCA and Vietnamese authorities.
  • Technical logs, engine health monitoring, and radio licenses.
  • Debris examination reports, including identification and analysis of various parts.
  • Air-ground communication logs and cargo manifests.
  • Laboratory test results on lithium batteries and mangosteen fruits.

VI. Key Viewpoints

• The disappearance of MH370 is a puzzle with no conclusive explanation.
• Human factors and air traffic control procedures were thoroughly investigated but did not provide a definitive cause.
• The satellite communication logs suggest potential anomalies, but their interpretation remains uncertain.
• Debris analysis did not confirm the location of the crash site or cause of the crash.
• Safety recommendations focus on improving procedures and system reliability to prevent similar incidents in the future.

VII. Summary

This report is a detailed safety investigation into the disappearance of MH370, focusing on flight path deviation, communication loss, and wreckage analysis. Despite extensive technical and human factor reviews, the exact cause remains unidentified. The recommendations aim to improve air traffic control, crew management, and aircraft monitoring systems. The report is comprehensive, covering factual data, analysis, findings, and safety improvements, and serves as a reference for aviation safety and regulatory updates.
