Faulty Lion Air jet sensor not fixed before crash, finds report

Bloomberg

A malfunctioning sensor at the centre of the investigation into the October 29 crash of a Lion Air jetliner into the Java Sea wasn’t repaired before the fatal flight even though it had failed on the plane’s previous trip, according to a preliminary investigative report.
A mechanic worked on other sensors and equipment during a night shift before the early morning departure, but not on the so-called angle-of-attack vane, according to
Indonesia’s National Transportation Safety Committee (NTSC).
The investigators also asked Lion Air to take corrective steps to improve the safety culture as they released the report in Jakarta.
The report doesn’t offer a cause for the accident that killed all 189 on board but provides the most detailed look so far into the chaotic minutes before the crash and into the steps that were taken to address malfunctions that occurred on the plane the previous night.
On both flights, pilots reported that they had difficulty figuring out basic information such as speed and altitude.
The pilots on Flight 610, which plunged into the Java Sea more than 11 minutes after it took off from Jakarta, appeared not to understand what was happening to them as they radioed air traffic controllers asking for their altitude and speed. They said they had an unspecified “flight control problems,” according to the report.
Lion Air Director Zwingly Silalahi said the airline was still studying the safety recommendations made by the investigators in the report for implementation.
Boeing said in a statement that its 737 Max series of jets are safe and it is working closely with investigators to assist the Indonesian probe.
