Investigators say anti-stall system activated before Ethiopian Airlines crash

"We still have confidence in the Boeing brand, but not the MAX 8 product, because the people, or our customers, have lost confidence in the product", he said, adding that he believed Boeing would support Garuda Indonesia, because, as a flag carrier, the airline was Boeing's key customer in Indonesia.

While investigators found that sensors had given wrong information about the angle of the plane before the Lion Air crash, neither the Indonesian or Ethiopian planes displayed warnings - - a safety feature sold as an optional extra.

In the lawsuit, the family says that Boeing failed to warn the public, airlines and pilots of the airplane's allegedly erroneous sensors, causing the aircraft to dive automatically and uncontrollably.

However, the source said the investigation is still underway and officials may still find another culprit in the tragedy.

The two crashes, barely five months apart, have claimed a total of 346 lives.

US Transportation Secretary requests formal audit of MAX certification
The FAA last week said it planned to mandate changes in the system to make it less likely to activate when there is no emergency. The agency and Boeing said they are also going to require additional training and references to it in flight manuals.


The European Aviation and Space Agency (EASA) certified the plane as safe in part because it said additional procedures and training would "clearly explain" to pilots the "unusual" situations in which they would need to manipulate a rarely used manual wheel to control, or "trim", the plane's angle. If the planes would need to remain grounded throughout the busy summer season, Tui predicts the costs would rise up to €300m and annual profit would be 26% lower than a year ago.

The US Department of Justice is investigating Boeing's development process, while the government is to review how the FAA certifies new aircraft, with questions being asked about the extent of self-certification by manufacturers.

In other words, Boeing will have some substantial liability in both crashes, and perhaps even in the costs associated with grounding the 737 Max fleet around the world. Boeing Co on April 27, 2016, reported a 9 percent drop in first-quarter profit, citing an after-tax charge from the KC-46 aerial refueling tanker it is developing for the U.S. Air Force. Boeing is still awaiting FAA approval on the software update. Data revealed that similarly to the Lion Air aircraft, the Ethiopian Boeing 737 MAX 8 experienced uneven climbs and descents just after taking off.

"We've revised our base-case timeline for the groundings to around two months because this MCAS fix appears mature, the MCAS upgrade should only take one hour per plane, and the updates will not require significant training", he wrote in a note. The investigation into the March crash, which is being led by the Ethiopian Transport Ministry, is still at an early stage.
