Surprising decision by the boss of Ethiopian Airlines
Only a mad dog will bite the hand that feeds him.

Boeing has invited more than 200 global airline pilots, technical leaders and regulators for an information session on Wednesday as it looks to return the 737 MAX to service. The software patch is nearing completion, then it will need regulatory approval.

Norwegian has decided to delay potential sales of six B737-800s and use available B787 capacity on high-volume routes, which will add flexibility amid the B737 MAX grounding. The carrier is further preparing to wet-lease aircraft to fill the remaining capacity gap. Norwegian is confident to reach a constructive agreement with Boeing.

Qatar Airways threw its support behind Boeing, but will delay the April 2019 delivery of a single MAX jet until the cause of the crash is known.

Samoa Airways says it will not take delivery of B737 MAX 9 after the two fatal crashes of MAX 8. The government will look for another B737-800 to continue its service once the lease of the current B737-800 from Neos (Italy) expires at the end of March 2019. The MAX 9 was to be leased from Air Lease Corp.

All these assumptions of what the pilots could have done to prevent this crash... as i mentionned already weeks ago; guys, they only got a couple of seconds at this agl ! and confirmed now in the news: simulation gave pilots 40 secs

Boeing said it had reprogrammed software on its B737 MAX to prevent erroneous data from triggering an anti-stall system.

https://www.aviation24.be/manufacturers ... egulators/

However, FAA said that it has not yet granted provisional approval for Boeing announced anti-stall software upgrade of B737 MAX. About letting Boeing certifying itself some equipment or processes, FAA said it would cost US$1.8 billion and take 10,000 new employees for it to handle all aircraft certification internally, while answering questions on how new planes are approved for flight.

American Airlines Group pilots’ union said they were pleased with Boeing’s progress on a B737 MAX fix but warned that the certification process should not be rushed or fast-tracked.

Investigators believe that the Boeing 737 MAX stall-prevention feature MCAS was activated in the Ethiopian crash. Emerging consensus is the strongest indication yet that the same MCAS system misfired in the fatal Ethiopian and Indonesian flights. (Paywall)

A lawsuit against Boeing Co was filed in US federal court on Thursday in what appeared to be the first (and probably not last) suit over a March 10 Ethiopian Airlines 737 MAX crash that killed 157 people.

The lawsuit was filed in Chicago federal court by the family of Jackson Musoni, a citizen of Rwanda, and alleges that Boeing, which manufactures the 737 MAX, had defectively designed the automated flight control system.

The complaint was filed by Musoni’s three minor children, who are Dutch citizens residing in Belgium.

"One emblem of the whole situation is that as the 737 MAX engineering team piled kludge on top of kludge, one thing they came up with was a cockpit warning light that would alert the pilots if the plane’s two angle-of-attack sensors disagreed.

But then, Boeing’s team decided to make the warning light an optional add-on.

The light cost $80,000 extra per plane and neither Lion Air nor Ethiopian chose to buy it, perhaps figuring that Boeing would not sell a plane (nor would the FAA allow it to) that was not basically safe to fly. In the wake of the crashes, Boeing has decided to revisit this decision and make the light standard on all aircraft
."

80,000 $ for a warning light? Those guys at Boeing know how to make money! And now it is costing them billions of $ ...

Meanwhile the Boeing stock has the same value than 6 months ago.
Ok everybody expect the 777x to be a success but everybody seems to ignore the dozens of court action flying their way
My messages reflect my personal opinion which may be different than yours. I beleive a forum is made to create a debate so I encourage people to express themselves, the way they want, with the ideas they want. I expect the same understanding in return.

Norwegian chief executive Bjorn Kjos will travel to visit Boeing and address problems linked to the recently grounded B737 MAX aircraft.

Ethiopia did not release a preliminary report into the causes of last month’s Ethiopian Airlines crash today, as previously expected, but may publish it later this week.

It looks like the 737 MAX will not fly any time soon...

An acft that needs software to compensate the deteroriation of aerodynamics should never fly again ! The old 737 wing design is not appropriate for the new and bigger eco engines, there is a point when retrofitting has to end, it has been going on for half a century for now...

Then scrap the F16 and many more combat planes!

The F16's aerodynamics has never been deteriorated! But this is a little off topic...

Actually its not, its about software augmentation/compensation to counter aerodynamic designs anomalies which MCAS is. And like Mr Olislagers says, most combat aircraft would just barely fly without the software that constantly arranges the flight surfaces to keep the plan aerodynamically stable. MCAS does this in a very basic way, there is no issue with that. The issue lies that (apparantly) the software is broken.

I would rather call it: lack of redundancy. If the system gets out of control by the wrong input of just one sensor then the basic rule in aviation is broken. Especially when the warning light, that informs the pilots of such event, is a quite expensive option.
