The CVR of the Boeing Co. 737 Max aircraft was intact when it was recovered in the Java Sea, according to said Agung Nugroho, a spokesman for Indonesian Navy’s first fleet command. The CVR, together with the flight data recorder that was found in November, are jointly known as the black box of an aircraft.

The crash survivable memory unit of the CVR will be taken to the National Transportation Safety Committee’s facilities for downloading the recording of the conversation and data, the agency said in a statement on Monday. It didn’t say how long it will take investigators to download the recording.

The CVR is intact even though it has some scratch marks and dents from the impact, Nugroho said. While lauding the efforts of authorities to recover the CVR, President Joko Widodo said the recording will help clarify the cause of the fatal crash.

Lion Air’s JT610 nose-dived into the Java Sea shortly after takeoff Oct. 29, killing all 189 on board to become the country’s worst air disaster in two decades. Poor safety procedures and the inability of pilots to gain control of a malfunctioning aircraft may have contributed to the crash, according to a preliminary report by Indonesian investigators in November.

Confusing Warnings

While the report didn’t specify the cause of the tragedy, it outlined how pilots handled confusing anti-stall warnings during the last two flights of the almost brand-new 737 Max 8. It also recommended that Lion Air improve its safety culture.

In response to the report, Boeing said the 737 Max series of jets is “as safe as any airplane that has ever flown.”

Lion Air’s co-founder, Rusdi Kirana, threatened in December to scrap aircraft orders from Boeing, saying he felt betrayed by the manufacturer’s reply. Lion Air is the third-largest buyer of the updated single-aisle plane from Boeing, behind Southwest Airlines and Flydubai. DM
