Indonesia stepped up its hunt for the second black box on a crashed Boeing Co. jet after four days of scouring the sea only yielded a single damaged flight data recorder, prolonging the mystery on what downed the Lion Air plane.
The devices are built to withstand high-impact crashes, and the shattered box shows how violently the 737 Max jet plunged and broke into pieces. An expert team from the U.S. National Transportation Safety Board, Federal Aviation Administration, Boeing and General Electric Co., the maker of aircraft engines, is assisting in the investigation, according to the Indonesian government.
While the force of the impact tore off exterior electronics and some of the recorder’s structure, the module holding the data-storage area appears in news photos to be intact and the unit should still be operable, said James Cash, a former NTSB investigator who’s processed thousands of such recorders.
“I’m sure that the memory is going to be great,” said Cash, who retired as the safety board’s chief technical adviser for recorders.
Indonesian President Joko Widodo, who met officers supervising the search operations in Jakarta on Friday, asked the National Transportation Safety Committee to work quickly to uncover the reasons for the crash. “We shouldn’t have any such accidents in the future,” he said. “Passengers’ safety must be made a priority.”
