SCORES of divers plunged into the Java Sea today to search the wreckage of an AirAsia jet for the black box recorders that could reveal why the plane crashed, Indonesia’s search and rescue agency said.
Flight QZ8501 vanished from radar screens over the northern Java Sea on December 28, less than half-way into a two-hour flight from Indonesia’s second-biggest city of Surabaya to Singapore. There were no survivors among the 162 people on board.
The cause of the crash remains a mystery, with hopes centring on the so-called black boxes â€“ the flight data recorder and the cockpit voice recorder â€“ providing vital clues. The plane which crashed was an Airbus A320-200, which carries the recorders near the tail section.
The tail of the plane was found yesterday, upturned on the sea bed about 30km from the plane’s last known location at a depth of around 28m to 32m.
“After we found the tail, our plan is to do everything step by step,” Fransiskus Bambang Soelistyo, head of the search and rescue agency, told a news conference in Jakarta.
“First we will (check whether) the black box is still at its place, in the tail, or if it has detached.”
A total of 84 divers are in ships in the vicinity and teams began searching the jet’s tail at 6.45am with visibility poor and strong currents still impeding efforts, Fransiskus added.
Should diving teams confirm the location of the recorders, the tail will probably be plucked out of the sea using a crane capable of lifting 70 tonnes.
Ships with acoustic “pinger locators” designed to pick up signals from the black boxes were at the location but were no longer being used, in a possible sign of confidence among Indonesian officials that the recorders will be found soon.
Two Japanese ships that were part of the international effort to find the plane would now leave the mission tomorrow, Fransiskus said.
“Now that the tail is confirmed, we are confident,” Mardjono Siswosuwarno, the main investigator of the National Transportation Safety Committee, said yesterday.
“In my opinion, the pinger locators are no longer necessary to finding the black box.”
Forty bodies and debris from the plane have been plucked from the surface of the waters off Borneo, but strong winds and high waves have been hampering divers’ efforts to reach larger pieces of suspected wreckage detected by sonar on the sea floor. â€“ Reuters
