Crashed Lion Air jet flew four times with damaged airspeed gauge

The Boeing 737 MAX 8

The U.S. plane maker said investigators probing the Lion Air crash off the coast of Indonesia that killed all 189 people aboard found that one of the "angle of attack" sensors on the Boeing 737 MAX aircraft had provided erroneous data.

The day before the crash, the Boeing 737 MAX 8 - which had only around 800 flying hours on the clock - had experienced a significant drop in altitude on a flight from Bali to Jakarta, passenger Robbi Gaharu said.

With the warning, pilots would be advised to stick to an existing procedure to tackle such situations. Under some circumstances, such as when pilots are flying manually, the Max jets will automatically try to push down the nose if they detect that an aerodynamic stall is possible, a person familiar with the matter said.

Lion Air confirmed to CNN that the same aircraft was used on that route, and Indonesian authorities confirmed that the pilot on the flight reported a problem with one of the plane's instruments.

The Lion Air 737 Max 8 dove into the Java Sea on October 29 minutes after takeoff, nosing downward so suddenly that it may have hit speeds of 600 miles an hour before slamming into the water.

Lion Air's Boeing 737 Max 8 lost contact with the control tower 13 minutes after it took off from Jakarta airport for Pangkal Pinang on the island of Bangka.

"We also plan to conduct a flight reconstruction to see the impact of the AOA sensor damage in the engineering simulator at the Boeing facility in Seattle". The plane went into a sudden dive minutes after takeoff, from which the pilots were able to recover.

"When there was a problem, the pilot would write it down and the mechanic would do (a repair).Then the plane would be declared airworthy".

In a statement on Tuesday, the airline manufacturer said it had issued an "Operations Manual Bulletin" advising airline operators how to address erroneous cockpit readings. If the angle is too extreme it can cause the wings to lose lift and the aircraft to stall.

United Technologies Corp. supplies the angle-of-attack sensors and indicator for the 737 Max, according to Airframers.net.

Indonesia's National Transportation Safety Committee earlier this week announced the plane had a malfunctioning airspeed indicator on its last four flights, based on analysis of the flight data recorder. "This is what we do not know yet and we will find it out, ' he said".

On Thursday (Nov 1), the SAR team found the flight data recorder (FDR) of the aircraft, and now the search focus was on another part of the aircraft's black box, namely, the Cockpit Voice Recorder (CVR).

At one stage during the conference, relatives urged Lion Air founder Rusdi Kirana, who was in the audience, to stand up. The crash is being blamed on a "technical issue", Soerjanto Tjahjono, the head of Indonesia's National Transportation Safety Committee, told victims' families Monday.

Wednesday night's incident involving Indonesian low- cost airline Lion Air comes as the authorities extend search efforts till Saturday for victims' bodies and a second black box from the downed Flight JT610. The aircraft's erratic behaviour during its final flight, and reports of an issue during a previous journey, had already prompted speculation that this could have been an issue.
