Divers have recovered the flight data recorder of the Boeing Max 8 that crashed in Indonesia last week, and investigators say it shows the airplane had indicated inaccurate airspeed readings for three days before the crash, The New York Times has reported.

Prior to the accident, Daniel said that Lion Air had held daily meetings with Boeing representatives in Indonesia and said that several announcements will be made in due course all of which is based on these meetings.

WestJet also has 9 of the 737 MAX jets in its fleet, but the airline did not immediately respond to a query about the Boeing bulletin from CBC News. A preliminary report is expected at the end of the month. The committee said the pilots were dealing with an erroneous airspeed indication. However, if the sensor malfunctions, it can cause the plane's computers to erroneously think it is in a stall - which can then command the aircraft to abruptly dive. The "angle of attack" is the angle of the airplane or its wings compared with oncoming air or wind.

Lion Air's Flight JT610 plunged into the Java Sea on October 29 shortly after take-off from Jakarta and killed everyone on board.

Bloomberg says the plane's velocity was uncharacteristically high, possibly touching speeds of 600 miles an hour as it hit the water.

The new details - gleaned from the flight data recorder - came after the government said it was launching a "special audit" of Lion Air's operations.

"If the nose is trimmed down on an aircraft, it becomes hard for the crew to hold it", said a person briefed on Boeing's bulletin, SeattleTimes reported.

Officials have now said that the incident will be thoroughly investigated.

Some modern aircraft have systems created to correct the posture of the wings automatically to keep flying safely.

Industry insiders said that the completion of the Zhoushan plant, announced amid ongoing China-US trade frictions, reflects US companies' heavy dependence on both the supply chain in China as well as the country's huge market.

"An investigation will be carried out by Aircraft Inspection and Airworthiness Inspector, Airport Inspector and Aviation Navigation Inspector to see the cause of the incident and the appropriate follow-up steps", Acting Director General of Air Transportation M Pramintohadi Sukarno said. The only way to prevent this, is for the pilot to intervene and manually deactivate the system.

Currently, Jet Airways and SpiceJet fly Boeing 737 MAX planes in India.

Pilots raise and lower the nose of Boeing jetliners by pushing and pulling on a yoke in the cockpit, which controls panels at the tail known as elevators. The aircraft system that handles the nose up and down movement (called stabilizer trim system) will put the nose down in response to the erroneous AOA sensor.

"The pilots can use extra force to correct the nose down trim, but the failure condition repeats itself, so that the nose-down push begins again 10 seconds after correcting", reported The Seattle Times.
