I understand that there have been two crashes but have there been instances of successful recovery? Would we ever know?
Those incidents would surely have been reported to Boeing.

For some reason USA pilots reported similar instances to NASA? One of the reasons I read on why USA stopped them from being flown.

If you look at the checklist above, everything above the dotted line are what’s called ‘memory items’. They must be performed from memory by the crew without reference to the QRH. There are quite a few of these checklists on the 737. Checklists that must be done from memory are that way because they are flight safety critical and need to be completed in a timely manner. The ‘Engine Fire or Engine Severe Damage or Separation’ checklist is another.

Once the memory items are done (and any other necessary tasks completed) we go back and do the whole checklist from the beginning for 2 reasons: 1. To confirm all the memory items are complete, and 2. to complete the reference items below the dotted line, which contain info of a less urgent nature, such as performance effects of the failure, and effects on the remainder of the flight, such as other systems degraded by the malfunction, and other relevant data. In this case, you stay in this checklist until landing. In other checklists, you might finish it and go back to the normal checklists for the remainder of the flight. It just depends on what the failure is.

Below is an example of running 2 checklists in the B777. The crew deal with an engine fire (all from memory). They only do the memory items of the first checklist as they are unable to extinguish the fire (more important to get the folks off than running through the reference items, which have no effect).
They then run the Evacuation Checklist (read and do - no memory items).

The scenario is similar on all Boeing jets.

Thanks for that.....I’d be not good as a pilot as my memory is shot.

No back up system?

This, on the face of it, would seem to be a major problem for Boeing. As two major accidents appear to have demonstrated, the MCAS is a flight critical system. For boeing to have either not recognised this, or recognised it and deliberately treated it as not being flight critical, puts them in a very bad position, highlighted by the fact that the 'AoA disagree' warning system was an extra cost options - and fitted to neither of these aircraft.

All it needs now to really put them in a bad position is for an internal memo to surface warning of this possible outcome. I have seen articles suggesting the root of the problem is the separation of management from engineering and the move of management from Seattle to Cicago, from where the company has been run by MBAs with no production or design experience.

I have afriend whom is an engineer with Qantas, he has said the moving of engineering to Singapore, is a an equally bad move.

The Boeing scandal is an indictment of Trump’s corporate America

I don't think it started with Trump, although Trump is the culmination of it. The watering down of government oversight in aviation goes back at least to GWBush, and possibly as far back as Reagan.

It started around the time the airline industry was de-regulated several decades ago, and this is the culmination of those decisions. Plenty of info online about it.
