Investigators say anti-stall system activated before Ethiopian Airlines crash

A Boeing Co. 737 MAX 9 jetliner sits on the production floor at the company's manufacturing facility in Renton Washington U.S. on Monday Feb. 13 2017. Boeing Co. is laying plans to expand the family of 737 Max jetliners with a new version tailor

The information was presented Thursday to United States authorities, including the Federal Aviation Administration (FAA), the source said. "But it's certainly creating fear and the lack of confidence in Boeing customers and those that trust the FAA", Guzzetti said.

USA safety investigators reviewed data from the "black boxes" that were aboard Ethiopian Airlines Flight 302, four people briefed on the investigation told Reuters on Thursday.

Attorney Steven Marks filed the first lawsuit against Boeing connected to the Max 8 crash in Ethiopia.

Boeing revealed updates to a scrutinized automated safety system in the new model on Wednesday while defending the original design, saying the software updates would make the design "more robust". A preliminary report on the Ethiopian Air crash is expected any day.

When the Boeing 737 MAX achieves speeds greater than 230 knots (265mph or 425kph), with its flaps retracted, pilots would potentially have to intervene using a wheel on the center console as opposed to an electric thumb switch to which they might be accustomed.

According to Ethiopian Airlines CEO Tewolde GebreMariam, pilots transitioning to the Boeing 737 Max 8 aircraft from older 737 models were required only to undertake a short computer-based training program prescribed by Boeing and approved by the FAA.

The planemaker said the anti-stall system, which is believed to have repeatedly forced the nose lower in at least one of the accidents, in Indonesia last October, would only do so once per event after sensing a problem, giving pilots more control.

Boeing is working on an update to the MCAS software so it's less aggressive about pointing the nose down and easier for pilots to override it.

Lion Air Flight 610 crashed into the Java Sea in Indonesia on October 29 after taking off from Jakarta.

"Boeing, having knowledge of all the reports of unsafe conditions and the previous accident that killed over 150 people, should have taken steps to protect the flying public", said attorney Steve Marks, who is representing Musoni's relatives, the Washington Post reported.

However, the published flight manual did not reference these "unusual" situations, according to a copy from American Airlines seen by Reuters, with tragic consequences and an overall death toll of 346 lives.

Cowen Research analysts say a "very rough guess" is that Boeing will pay about $US2 billion after insurance to fix the plane, pay crash victims' families and compensate airlines that had to cancel flights.

Pilots were unable to regain control and prevent disaster, and the Lion Air flight eventually crashed in the Java Sea, killing 189 people.

On the 737 MAX, Boeing removed the "yoke jerk" function that enabled pilots to disable the automated trim system with a hard pull on the control column rather than hitting two cut-out switches on the center console. 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.

"[Boeing officials] have to discuss the matter internally", said Garuda Indonesia president director Ari Askhara in Nusa Dua, Bali, on Friday, as reported by Antara.
