Final Air India Crash Report Remains Pending Due to Ongoing Analysis and International Review Processes

The final report into the Air India Boeing 787 crash is still pending one year after the incident because investigators are continuing to analyse a wide range of evidence, including complex engine components, and must complete required international reviews. The Aircraft Accident Investigation Bureau (AAIB) has indicated significant progress in examining aircraft systems, flight recorder data, and operational records, but has not provided a definitive timeline for the report's issuance.
Extensive Examination of Aircraft and Operational Data Underway

The AAIB has conducted an "extensive and rigorous examination" encompassing technical, operational, organisational, and human factors over the past year. This includes a thorough analysis of the aircraft's systems, data from the flight recorders, and all relevant maintenance and operational records. This detailed review is a crucial step in understanding the sequence of events leading to the crash of Flight AI171.
Complexity of Engine Component Analysis Contributes to Delay

A significant factor contributing to the delay in finalising the report is the complexity involved in analysing the plane's engines. Early findings from a preliminary report indicated that the Boeing 787's engine fuel control switches moved almost simultaneously from the 'RUN' to the 'CUTOFF' position, leading to both engines being starved of fuel shortly after takeoff. The detailed forensic examination of these components is a time-consuming but essential part of the investigation.
International Review Process Required Before Report Issuance

Under international aviation accident investigation rules, a final report is ideally expected within one year of an accident. However, if this deadline cannot be met, authorities are required to issue an interim statement on each anniversary of the event. The AAIB has stated that the final report will only be issued after all investigative work is completed and the necessary international reviews have been carried out, a process that adds to the overall timeline.
Families of Victims Seek Clarity Amidst Investigation Delays

On the first anniversary of the crash, which claimed the lives of 260 people, families of the victims continued to press for answers and expressed scepticism over the lack of a definitive timeline. While the AAIB has assured that significant progress has been made, the absence of a final cause has been difficult for those mourning their loved ones, with some still awaiting the return of personal belongings.
