    Ethiopian Max 8 crash

    https://aviation-safety.net/database...?id=20190310-0

    Breaking news that this plane crashed two hours ago with 157 occupants. Aircraft is written off, no details of casualties yet. Plane was four months old and contact was lost six minutes after take off. R.I.P.

    Indication reported that the plane have eratic speed patern after take off. This reminds too much like the Lion Air Max 8 crash.
    Not a good development for Max 8 and Boeing.

      Well Dreamliner and this possibly will effectively end Boeing as an aeroplane maker...IMHO.

        This accident will have almost nothing to do with the future of Boeing. The engineers will find the problem and fix it for 100 %. Some airlines have grounded their planes as a precaution. One black box, damaged, has been found, not clear yet which one it is.

          A terrible tragedy. R.I.P. and condolences to the bereaved.

          Both flight recorders have been retrieved apparently.

              And why would this be any different than AF 447?
              We seem to get the same message anytime there is a Boeing crash.

              It would take a major airframe design issue to hurt Boeing, this is likely a systems issue if it is the same as the other recent MAX crash.
              At any rate Boeing is well diversified with many programs, civil and military.
              Sorry to disappoint you.





              There are two sides to every story. The truth is usually somewhere between the two.

                Would like to take credit for that, but my iinformation on Dow Boeing shows a fall of 6.5 % ?!

                  This accidents involving Max8, will not put an end to Boeing. However it will give more momentum to A320NEO family.
                  When A320 got accidents like example the one involve Air Asia A320, it make some potential buyers switch to 737. However for Airlines that already depends with 737...or A320 they will not change easily like that.

                  Lion Air despite some heated word exchange with Boeing after the MAX8 accident...where Boeing indicating the fault on Lion Air maintenance, and Lion Air exchange it with potential faulty parts on MAX8, send threatened to move to A320..in reality for Low Cost Airlines it won't be easy to change fleets as their cost structures related to one or maximum two kind of aircraft in the fleet.

                  It will be interesting to see if this also provide some additional momentum to C919 or MC-21..
                  World Airlines just need alternative from 737 and 320.

                          Wehn they changed the engines (bigger), they also had to change their position on the wing. This changed quite obviously changed the aircraft behaviour and they applied a patch instead of rewriting the FCS. Result, pb with tail satbilizers. Do not know at all it this is the cause. It might be.

                            From a good source elsewhere

                            Basically the problem is that as they've lengthened the aircraft and added larger diameter engines, the aircraft's pitch stability has become an issue. At high angles of stack the engine nacelles themselves create lift forward of the CG, causing the aircraft to pitch up into a stall with no pilot input. This is obviously streng verboten in the certification requirements hence MCAS. Stability augmentation isn't a new thing - the 737 already has a speed trim system and a Mach trim system from the early days, it's just the new one is subject to some nasty failure modes, about which some duff assumptions were made, and nobody thought it was important to tell the crews flying it anything about it.
                            Lots of people have died. It might be more respectful if this didn't continue as a childish fanboi bicker-fest.

                              This first video explains the MCAS system, and was made at the time of the Lion Air 737 Max accident: -



                              And more info on the trim system (made in response to recent findings of the Ethiopian 737 Max crash): -
