Chairs, wheels and other parts of a crashed Indonesian Lion Air jet were hauled from the depths on Friday, as authorities analysed black box data that may explain why the new plane plummeted into the Java Sea, killing 189 people.
He said the Directorate-General of Air Transportation has asked Lion Air to remove four key officials from duty - its director of maintenance and engineering, quality control manager, flight maintenance manager and release manager - so they can assist the investigation.
Lion Air has ordered 50 of the MAX 8 planes and one of its subsidiary airlines was the first to operate the new generation jet a year ago.
This was reported by the Committee on safety of transportation of Indonesia, referring to Sky News reports RBC-Ukraine.
The shattering of the device, which is built to withstand high-impact crashes, shows how violently the 737 Max jet plunged and broke into pieces.
"The underwater current was strong, so visually we haven't been able to see the black boxes", Syaugi said. The search area has been doubled to 10 nautical miles.
It should be recalled, on 29 October off the coast of Indonesia crashed airliner, Boeing 737 MAX, which was flying JT610 in pangkal Pinang. The pilot had already received permission to return to base.
A diver identified as Hendra said the box had been buried in debris on the floor of the Java Sea.
"Because of the Pan-Pan call, we were told to hold off, circling the airport in the air", the pilot said.
Results of a preliminary investigation will be made public after 30 days, one official on the investigation team said.
Hopes are fading of finding a large section of fuselage intact, with easily retrievable bodies inside.
"Hopefully that is the main body of the plane that we've been looking for". The devices help explain almost 90 per cent of all crashes, according to aviation experts.
The Lion Air flight JT 610 flown by Indian captain Bhavye Suneja disappeared from the radars on Monday morning, 13 minutes after it took off.
The privately owned budget carrier was founded in 1999. In the context of Indonesia's patchy aviation safety record, however, lawmakers have started to call for a tightening of standards and a government-led audit of the country's airlines.
It will now be subjected to more intensive "on ramp" inspections than other airlines, authorities said.
The minister also said that airlines were required to conduct processes to determine the aircraft's fitness for flight, such as periodic maintenance, during the documents' validity periods.
Indonesia is one of the world's fastest-growing aviation markets.
Though the airline Lion Air said that the aircraft was fully serviceable.
Lion Air CEO Edward Siriat said the plane had a technical issue which was resolved according to the procedure.
The news agency also quoted a pilot of another plane approaching Bali at the time and able to listen to a radio conversation between the Lion Air pilot and air traffic controllers.
