Ping From Lion Air Jet's Cockpit Voice Recorder Is Disappearing

Searchers trying to locate the cockpit voice recorder of the Lion Air jet that crashed into the Java Sea off Indonesia face a new challenge as an electronic signal from the device fades.

“The ping sound is getting hard to detect and is disappearing,” according to Haryo Satmiko, deputy chief of Indonesia’s National Transportation Safety Committee. A new underwater locator with better sensitivity to detect the ping from the so-called black box is ready for deployment to help the search.

If that fails, the safety committee will deploy a ship with mud-suction ability to try to recover the voice recorder.

“We suspect the cockpit voice recorder is covered by mud because the flight data recorder, when it was found, was about a half meter deep buried in the mud,” Satmiko said by text message Saturday.

The recovery of the voice recorder would help investigators piece together the final moments before flight JT610 dove into the sea with 189 people on board on Oct. 29. Preliminary findings based on information from the data recorder, which has been recovered, indicated a technical snag related to faulty airspeed reading.
