Divers to Investigate Pings That May Be From Airasia Flight 8501
Surabaya, Indonesia (CNN)- Divers are preparing to investigate underwater pings that may be coming from the flight recorders of AirAsia Flight QZ8501, Indonesia’s military chief said Friday.
An Indonesian search vessel had earlier detected the pings, said Gen. Moeldoko, the head of Indonesia’s armed forces.
He was speaking on board the ship that is being used as a base for divers trying to raise the tail of the AirAsia plane, which went down in the Java Sea on December 28 with 162 people on board.
But there is also caution surrounding the possible pings, because the sound could be emanating from other sources. In the case of Malaysia Airlines Flight MH370, several signals raised hopes of locating the missing plane, but proved to be false leads.
Search teams, which had been battling bad weather and strong currents, found the tail section on the sea floor Wednesday.
That discovery was seen as significant because in the Airbus A320-200, the aircraft model of Flight QZ8501, the flight data recorder and cockpit voice recorder are housed in the tail.
But before Friday, searchers hadn’t reported detecting any possible pings from the locator beacons on the flight recorders, which are popularly known as black boxes. It was unclear whether the devices remained inside the tail or had come free.
Batteries that send out the pings last 30 days. It has been 13 days since the AirAsia plane fell into the sea.
Conditions cleared up Friday, as divers prepared for a complicated operation to raise the tail to find the recorders.
Divers are lowering ropes and slings down to the tail. The plan is to inflate giant airbags or balloons underneath to lift the tail from the bottom of the sea. A crane would then be used to raise the section.
Search officials said that the underwater visibility and currents are much better than conditions in previous days.
