Divers retrieved the cockpit voice recorder from the wreck of an AirAsia passenger jet on Tuesday, MetroTV said quoting a transport official, a key piece of evidence for investigators to determine the cause of the crash that killed 162 people.
The cockpit voice recorder, which records conversations between the pilots and with air traffic controllers, was found close to where the flight data recorder was recovered from the bottom of the Java Sea on Monday, the report said.
The Airbus A320-200 airliner lost contact with air traffic control in bad weather on Dec. 28, less than halfway into a two-hour flight from Indonesia's second-biggest city of Surabaya to Singapore. There were no survivors.
The black boxes contain a wealth of data that will be crucial for investigators piecing together the sequence of events that led to the airliner plunging into the sea.
The cockpit voice recorder was now on board an Indonesian navy vessel and expected to be sent to the capital, Jakarta, for analysis, MetroTV said.
Investigators may need up to a month to get a complete reading of the data.
Dozens of Indonesian navy divers took advantage of calmer weather this week to retrieve the black boxes and now hope to find the fuselage of the Airbus.
Forty-eight bodies have been retrieved from the Java Sea and brought to Surabaya for identification. Searchers believe more bodies will be found in the plane's fuselage.
AirAsia cockpit voice recorder recovered
Indonesian divers have retrieved the cockpit voice recorder from beneath the wreckage of an AirAsia plane that crashed into the Java Sea as the airline's boss vowed to overcome the 'toughest times' he has known.
It came a day after the plane's other black box, the flight data recorder, was recovered, and the devices should provide investigators with vital information about what caused the accident.
Flight QZ8501 went down on December 28 in stormy weather as it flew from the Indonesian city of Surabaya to Singapore with 162 people on board.
Just 48 bodies have so far been recovered, with many believed to be in the main section of fuselage, which has not yet been found.
Indonesia's meteorological agency has said that the bad weather likely caused the Airbus A320-200 to crash, but a definitive answer is impossible without the data recorders.
Rescuers faced a lengthy, difficult search often hampered by bad weather but a key breakthrough came at the weekend when they finally detected 'ping' signals from the black boxes.
On Tuesday, an official involved with the search, who requested anonymity, confirmed that the cockpit voice recorder 'has been found and lifted from the sea'. The official added that the device had been taken to the navy ship Banda Aceh.
The flight data recorder monitors information such as airspeed, 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.
The accident is the first major setback for Malaysia-based AirAsia, which has enjoyed a 13-year run of success.
But its boss, Tony Fernandes, pledged on Tuesday that the airline would overcome the crisis.
' Rest assured, we are committed to reviewing and improving our products and services. We are more focused than ever to provide you with nothing but the best,' he said in a message.
'Even in our toughest times, we will continue to be the world's best and be better for you.'
Officials have said they believe the flight data recorder is in good condition and it has already been flown to Jakarta.
Indonesia's National Transport Safety Committee said the boxes would undergo a lengthy analysis in the capital, with the help of a team of experts, including from France and aeroplane 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.
Officials on Monday revealed dramatic new details of the accident, saying a rapid change in pressure caused the plane to 'explode' as it hit the water.
'It exploded because of the pressure,' said SB Supriyadi, a director from the search and rescue agency.
'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.'
Forty-eight bodies have been recovered so far, but the weather has hampered efforts to locate all the victims and the wreckage.
