The international aviation community offered assistance, with experts from Boeing and other agencies providing technical support. The search and rescue operation highlighted the challenges of conducting such operations in a maritime environment, particularly with the added complexities of identifying and recovering human remains.
Investigation and Findings
The National Transportation Safety Committee (KNKT) of Indonesia launched a thorough investigation into the crash. The analysis of the flight data recorder (FDR) and cockpit voice recorder (CVR) provided critical insights into the final moments of the flight. The FDR revealed that the aircraft's autopilot system was engaged during the flight. However, shortly after reaching its cruising altitude, the aircraft experienced a sharp roll to the left, followed by a steep dive. The CVR captured the conversations between the pilots, but there were no indications of distress or mechanical issues reported before the sudden descent. The investigation focused on several potential factors, including mechanical failure, human error, and weather conditions.
Initial findings indicated that the aircraft's engine thrust asymmetry might have played a role in the crash. The FDR data showed that one engine's thrust lever moved back slightly before the plane began its dive, creating an imbalance in power. While the cause of this asymmetry was investigated, the KNKT did not find evidence of a pre-existing mechanical problem with the engines. The investigation also considered the possibility of pilot error or disorientation. However, the experience levels of the pilots and the lack of any reported issues before the crash made this less likely. Weather conditions were also examined, but there was no indication that severe turbulence or other weather phenomena contributed to the accident. The KNKT released its preliminary report within a month of the crash, providing a factual account of the events leading up to the accident. The final report, released in 2022, concluded that a combination of factors, including a possible malfunction of the aircraft's auto-throttle system and the crew's response, led to the crash.
