Boeing signals flight control system problem may have contributed to 737 crash

An issue arose in 2016 at Rostov-on-Don Airport in Russia when a FlyDubai 737-800 nosed over and slammed into the runway at a steep angle, according to an interim report by Russian investigators.

What caused the plane to crash?

Boeing, which manufactured the Lion Air plane, issues safety-related bulletins, and had previously circulated instructions about what flight crews should do if sensors fail.

"There were four flights in all that suffered a problem with the airspeed indicator", NTSC head Soerjanto Tjahjono told reporters.

While the ultimate cause of the crash is still under investigation, Boeing has previously provided guidance on how pilots should deal with extreme nose down incidents.

It has not been determined whether those incorrect readings played any role in the October 29 crash.

Boeing has delivered 219 Max planes - the latest and most advanced 737 jets - since the models made their commercial debut past year with a Lion Air subsidiary. Of course, this is something they already overwhelmingly do, as we can see from the generally incredible recent safety record in global aviation, but clearly something went very wrong here that shouldn't have.

Lion has been a regular target of complaints about poor service, unreliable scheduling and safety issues, including a fatal 2004 crash.

"Any action that the FAA would take regarding that incident would have to wait until we have findings", agency acting Administrator Daniel Elwell said Monday after a speaking engagement in Washington.

AMC personnel of the airport had been questioned by the authorities over the accident, he added.

There are also procedures for pilots to follow in the event of missing data from damaged sensors on the fuselage skin, but it remains unclear how much time the crew of flight JT610 had to respond at the relatively low level at which they were flying.

"We are not flawless human beings", he said, sobbing.

The 2-month-old Boeing 737 MAX 8 crashed into the Java Sea 13 minutes after takeoff from Jakarta. Based on the bulletin, it appears that the nose of the Lion Air aircraft pitched down during the climb-out phase in response to an erroneous input from the sensor.

The accident has resurrected concerns about Indonesia's poor air safety record, which until recently saw its carriers facing years-long bans from entering European Union and U.S. airspace.

The US planemaker said investigators looking into the Lion Air crash had found that one of the "angle of attack" sensors on the aircraft had provided erroneous data. There were no survivors.

A Lion Air plane has smashed into an lamp post before take-off just a week after one of the airline's jets crashed in Indonesia killing 189 people.

But the preliminary result of the investigation will only be known at the end of November.

Indonesia's search and rescue agency said the search effort will continue until Sunday. Another clue: the so-called angle-of-attack sensor had failed on an earlier flight and had been replaced the previous day.

The same model of plane is regularly flown into Cairns and Darwin by budget airline Silk Air, while Virgin Australia has ordered 30 of them which are due to be in use in a year.
