Investigation Process and Findings

The investigation into the Sriwijaya Air Flight 182 crash was led by Indonesia's National Transportation Safety Committee (KNKT). The process involved a thorough examination of all available evidence, including the flight recorders, aircraft wreckage, maintenance records, and air traffic control data. Investigators also interviewed pilots, air traffic controllers, airline personnel, and other relevant parties to gather additional information and insights. The KNKT worked closely with international experts, including representatives from Boeing and the U.S. National Transportation Safety Board (NTSB), to ensure a comprehensive and objective analysis. The investigation followed a systematic approach, adhering to international standards and best practices for air accident investigations.

The data from the flight recorders revealed critical details about the aircraft's final moments. The FDR showed that shortly after takeoff, the aircraft experienced an unusual roll to the left, followed by a steep dive into the sea. The CVR captured the pilots' communications, providing insights into their actions and responses during the emergency. Analysis of the wreckage did not reveal any evidence of pre-impact structural failure or explosion. However, investigators focused on potential issues with the aircraft's autopilot system and the pilots' response to the unexpected roll. The final report, released by the KNKT, identified a combination of factors that contributed to the crash, including a possible malfunction of the aircraft's automatic throttle system and the pilots' decision-making under pressure. The report also highlighted the importance of improved pilot training and maintenance procedures to prevent similar incidents in the future. The findings from the investigation have been used to issue safety recommendations aimed at enhancing aviation safety standards both in Indonesia and globally.

Probable Causes and Contributing Factors

The probable causes of the Sriwijaya Air Flight 182 crash, as determined by the investigation, involved a complex interplay of factors. The primary cause was identified as a malfunction in the aircraft's automatic throttle system, which led to an asymmetry in engine power. This asymmetry caused the aircraft to roll unexpectedly to the left. The pilots' response to this emergency was also a contributing factor. The investigation suggested that they may have experienced spatial disorientation, which impaired their ability to effectively control the aircraft. Spatial disorientation is a condition where pilots lose their sense of orientation, altitude, or movement, often leading to incorrect control inputs.

In addition to the technical and human factors, the investigation also examined the role of maintenance procedures and crew resource management. The maintenance records of the aircraft were scrutinized to identify any potential issues that may have contributed to the throttle malfunction. The crew resource management (CRM) practices of the flight crew were also evaluated to assess how effectively they worked together to address the emergency. CRM involves the effective coordination and communication among flight crew members to ensure safe and efficient operations. The investigation highlighted areas where improvements could be made in both maintenance procedures and CRM training to enhance aviation safety.
