Boeing software re-activated before Ethiopian crash

Boeing software re-activated before Ethiopian crash

The problems on board the Ethiopian Airlines flight mirror those encountered on the doomed Lion Air flight 610 - which operated the same 737 Max 8 model and crashed in October - in what could be a major blow to Boeing as it struggles to get the aircraft back in service.

Following the news conference, Ethiopian Airlines released a statement saying: "The preliminary report clearly showed that the Ethiopian Airlines pilots who were commanding flight ET302 have followed the Boeing recommended and FAA approved emergency procedures to handle the most hard emergency situation created on the airplane".

The ongoing investigation into the crash is expected to conclude within a year.

Boeing Co, whose shares rose 2.4 percent on Thursday but were still below their level before the crash, said its software fix for its anti-stall system would give pilots the authority to always override the system if activated by faulty sensor data.

Faulty sensors on the Boeing Max jet led to the Ethiopian Airlines crash in March that spurred an global grounding of the fleet and launched numerous federal investigations by the USA government, the Chicago-based manufacturer said on Thursday. That will be addressed in the final report, she said.

U.S. President Donald Trump followed suit and grounded all Boeing 737 Max planes. The FAA has said it will review the software before allowing the Max to fly again.

Boeing is reportedly developing an upgrade of the software to USA regulators in a fortnight and is including added training in the near future.

The Journal says the pilots turned off the motors controlled by the automated anti-stall feature in an effort to regain manual control.

Both planes were relatively new 737 MAX 8 aircraft and both displayed similar flight behavior just prior to the crash, indicating that the MCAS system may have been linked to both crashes.

According Reuters, the pilots of Ethiopian Airlines Flight 302 did what they were supposed to do in order to take control of the plane, but the software may have re-engaged "as many as four times". The subsequent crash killed all 157 people on board the aircraft.

Investigators are studying whether there are any conditions under which MCAS could reactivate itself automatically, without the pilots reversing the cut-out maneuver. In the US, the Transportation Department has ordered a full audit of the FAA's 2017 certification of the Max and the Justice Department is also investigating.

In accordance with global rules, the preliminary report did not assign any blame for the crash.

Last month, The Seattle Times reported that an analysis Boeing delivered to the Federal Aviation Administration regarding the safety of MCAS "had several crucial flaws".

The authorities have yet to draw a firm conclusion on what caused the crash, but they are recommending Boeing review its system, WSJ said.

"Your Safety will remain our top most priority and we willcontinue to work together with our partners around the world to make air travel saferand more comfortable".
