Indonesian investigators are reportedly preparing to release the final report into last year’s fatal crash of Lion Air Boeing 737 MAX by October 2019. The findings, which follow a preliminary report published only a month after the accident took place, are expected to shed more light into the cause of the crash.

According to a statement by Indonesia’s director general of civil aviation Polana Pramesti on August 9, 2019, the final report into the crash of Lion Air Flight JT610 is expected to be published next month, after authorities receive feedback from the relevant parties. The National Transportation Safety Committee (KNKT) will be sending a draft of the report to Boeing, Lion Air, the U.S. Federal Aviation Administration (FAA), and other bodies, in the days to come, Reuters writes.

In a separate statement on August 9, 2019, KNKT’s lead investigator on the Lion Air crash Nurcahyo Utomo, noted that the agency is still awaiting data from Boeing: "When we get that data, it will go into our draft of the final report that we'll send to stakeholders, including Boeing, Lion Air and the US Federal Aviation Administration for feedback," he was quoted as saying by Channel News Asia citing AFP. According to Utomo, he expects the report to be released in October 2019.

Lion Air Boeing 737 MAX 8, operating Flight JT610, crashed into the sea shortly after take-off from Jakarta in October 2018, killing all 189 people on board. KNKT released a preliminary report into the accident the following month, in November 2018. At the time, the findings of the report were based on data retrieved from the flight data recorder (DFRD), drawing attention to Boeing’s new anti-stall system (MCAS).
