Boeing warns pilots about 'angle of attack' sensors after 737 MAX crash

Earlier this week, Indonesian officials hinted that airspeed indicators played a role in the deadly October 29 crash that killed all 189 people on board.

Boeing is preparing to send a warning to all the operators that have taken delivery of its new 737 Max aircraft, according to an anonymous source cited by Bloomberg. Spokesman Danang Mandala Prihantaro said that the plane was receiving directions from the aircraft movement controller on the tarmac, who too is being questioned.

Images distributed on social media showed passengers on the runway observing the broken part of the plane.

This comes in the wake of a new Lion Air Boeing 737 MAX crashing into the sea not long after leaving Jakarta, Indonesia, and killing all 189 passengers on board.

The pilot of the flight requested a return to Denpasar but the situation corrected itself and he elected to continue to Jakarta. Boeing released a bulletin about the issue on November 6.

But more importantly, the investigation-led by Indonesian authorities with the cooperation of Boeing and the U.S. National Transportation Safety Board-will determine what changes should happen to not only prevent the sensor failure from reoccurring, but hopefully also prevent such a failure from spiraling so horribly out of control even when it does happen.

"We don't know what the crew knew and didn't know yet", Cox said.

The bulletin from Boeing will say that erroneous readings from the jet's flight-monitoring system can cause the planes to "abruptly dive", the newspapaer reported on Wednesday, citing a person familiar fight the company's plans.

Boeing said the action was taken after the Indonesia's National Transportation Safety Committee indicated that the Lion Air jet experienced erroneous input from one of those sensors.

The plane maker said local aviation officials believed pilots might have been given wrong information by the plane's automated systems before the fatal 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.

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.

Airline safety experts said pilots are trained to handle a plane safely if those crucial sensors fail and backup systems are generally in place as well.

Search and rescue agency head Muhammad Syaugi tearfully apologised Monday as relatives' clamour for answers grew louder, with accusations that the pace of recovery is lagging.

Divers have recovered one of the two "black boxes" - the flight data recorder - but are still searching for the cockpit voice recorder, in the hope that it will shed more light on the cause of the disaster.
