AirAsia: Second black box recovered

JAKARTA  Indonesian divers Monday retrieved the flight data recorder of the AirAsia plane that went down in the Java Sea with 162 people on board, a potential breakthrough in efforts to discover what caused the crash.
The second black box, the cockpit voice recorder, was spotted by divers a short distance from the first but they had not yet managed to retrieve it because it was trapped under wreckage, officials said.
They also gave new dramatic details of the accident, saying a rapid change in pressure caused the plane to “explode” as it hit the water.
Navy divers brought the flight data recorder to the surface early in the morning, said national rescue chief Bambang Soelistyo, after a fortnight-long frustrating search often hampered by bad weather.

S.B. Supriyadi, a director with the rescue agency, said efforts would resume Tuesday to recover the second recorder, which was about 20 metres (65 feet) from the first and trapped under a wing.
He told reporters in Pangkalan Bun on Borneo island, the search headquarters, that giant balloons might be used to raise the wing so that the device could be retrieved.
The flight data recorder monitors information such as airspeed and heading, while the cockpit voice recorder stores radio transmissions and sounds in the cockpit. Both are located near the rear of the plane and designed to survive underwater.
Flight QZ8501 crashed 28 December on a short journey from the Indonesian city of Surabaya to Singapore. Indonesia’s meteorological agency has said stormy weather likely caused the Airbus A320-200 to go down but a definitive answer is impossible without the data recorders.
After a lengthy search, rescuers on Sunday detected “ping” signals from the recorders’ emergency transmitters close to what was initially thought to be the main body of the plane.
The flight data recorder of AirAsia QZ8501 is transferred to another container at the airbase in Pangkalan BunHowever Indonesian military chief Moeldoko told reporters aboard navy ship the KRI Banda Aceh that the main cabin, which is believed to contain most of the victims, had not yet been found. Just 48 bodies have so far been recovered.
Officials said they believe the flight data recorder is in good condition and it was being flown to Jakarta on Monday. Indonesia’s National Transport Safety Committee said it would undergo a lengthy analysis in the capital, with the help of a team of experts including from France and manufacturer Airbus.
The committee has said a preliminary report on the accident will be produced within a month, and a final report after a year.
Supriyadi said initial analysis of the wreckage so far recovered indicated that the plane broke apart on impact with the water.
“It exploded because of the pressure,” he said.
“The cabin was pressurised and before the pressure of the cabin could be adjusted, it went down — boom. That explosion was heard in the area.”
The search has involved US, Chinese and other international naval ships.
The tail of the plane, with its red AirAsia logo, was lifted out of the water on Saturday using giant balloons and a crane. It was brought by tugboat on Sunday to a port near Pangkalan Bun.

The bodies of a South Korean couple were identified on Sunday, but their 11-month-old baby remains unaccounted for.
The other foreigners were one Singaporean, one Malaysian, one Briton and a Frenchman — co-pilot Remi Plesel. Their bodies have not been recovered.
While the cause of the crash is unknown, the disaster has once again placed Indonesia’s chaotic aviation industry under scrutiny.
Indonesian officials have alleged Indonesia AirAsia did not have a licence to fly the route on the day of the crash, although the airline rejects the claim.
Indonesia’s transport ministry quickly banned AirAsia from flying the Surabaya-Singapore route.
On Friday it suspended dozens more routes operated by five other domestic airlines for similar licence violations.
