Jakarta/Singapore: Divers on Tuesday retrieved the cockpit voice recorder and may have located the fuselage of the crashed AirAsia jet in the Java Sea as experts will now use data from the two crucial black box devices to determine the sequence of events that brought the flight down.
The cockpit voice recorder, that possesses the last two hours of conversation between the pilots and with air traffic controllers, was found close to where the flight data recorder was recovered from the bottom of the choppy waters yesterday.
It was freed from beneath the heavy ruins of a wing early in the morning from a depth of about 30 metres, said Tonny Budiono, sea navigation director at Indonesia's Transportation Ministry.
This comes as a major potential breakthrough to solve the mystery of the Airbus A320-200's fatal crash on December 28 that killed all 162 people on board, after days of multi- national efforts to scour the seabed were hampered by bad weather.
Divers took advantage of calmer mornings yesterday and today to retrieve the black box - designed to survive extreme heat and pressure - usually inside the tail section but found missing from the wreckage when it was pulled out.
Earlier, an official said the cockpit voice recorder - part of two recorders that make up the black box - was on an Indonesian navy ship and and will be flown to Jakarta to be downloaded and analysed with the flight data recorder.
"This is good news for investigators to reveal the cause of the plane crash," said Tonny Budiono, sea navigation director at the Transportation Ministry.
"Today we have completed searching for the main things that we have been looking for," Rear Admiral Widodo, the commander of the navy's western fleet, told reporters.
"But the team will still try to find the body of the plane in case there are still bodies inside," he said.
Only 48 bodies, including at least two strapped to their seats, have been found in the choppy waters so far despite over two weeks of search operations.
The black box recorders, which are actually orange, are expected to shed new light on the mysterious crash that claimed all 162 lives on board the ill-fated AirAsia Flight QZ8501, en route from Indonesia's Surabaya city to Singapore.
Investigators may need up to a month to get a complete reading of the data to determine what caused the AirAsia group's first fatal accident half way into a two-hour flight.
Since the device records in a two-hour loop, all discussions between the captain and co-pilot should be available.
In another crucial development today, divers may have found one of the plane's engines that has a control unit to record data about performance, said Nurcahyo Utomo from the transport committee.
"If something is wrong with the engine, or weird, it will be recorded," he said.
