Its a 737-500, doubt people will be able to blame MCAS for it. Will need to wait for the NTSB to investigate and draw a conclusion as to what the cause of the accident is. Airlines are unlikely to park all 737's because there was an accident that happened and no one knows the reason of the accident yet. Could be one of many things that happened. Can happen to any plane easily regardless of who the manufacturer isDepends on the cause, more of the same?
