10 days feels like a lot of rush and get it done We can be hundred per cent sure that work on a MCAS software fix started as soon as the data from the Lion Air crash were available (several months ago). What's more, there is some suspicion that its certification and introduction was delayed by the US government shutdown earlier this year. So, the software fix might well be quite advanced now. The problem Boeing and the FAA are facing is lack of trust - a backlash from Boeing's denial and the belated grounding by the FAA. The fix might be ready, but how do we know ?

The fix was a reaction to the Lion air accident. But now we have the Ethiopian accident as well. The ET-pilots had received additional MCAS-awareness and special training with Lion air lessons learned. I doubt that some Lion air fix can be enough now. We need to know first what happened to ET.
There will be a lot of industry pressure on the FAA to end the grounding in the US. But I don't see the rest of the world following as fast as they did in the past. The public pressure on aviation authorities is very high at the moment to not clear it without fully understanding what happened and to make sure to prevent similar accidents from happening again.

EASA boss Ky said today at the EU parliament EASA intends to do a new, full EASA certification for the 737. They don't want to just rubber stamp the existing US certification like they did before.

Quite right too after some of the indications recently perhaps.

Canada is said to do another "own" certification like EASA now.

We need to know first what happened to ET. Of course ! Boeing must hope that both accidents are similar, so that a 'Lion Air fix' would solve all problems. The initial impression was that the pilots needed better training to react correctly when the MCAS is activated. Now that Boeing admits that a software upgrade is necessary, safety isn't going to depend on better training only. The billion dollar question is whether upcoming software improvements will be enough to make the MAX as safe as other airliners. Boeing would be in dire straits if an accident, or even a near-miss (or should I say a 'near-hit' ?), happened after the software has been updated.

The Ethiopian pilots had received a special MCAS training after Lion Air according to the ET-CEO.

EASA boss Ky said today at the EU parliament EASA intends to do a new, full EASA certification for the 737. They don't want to just rubber stamp the existing US certification like they did before. This is the approach I expect regulatory bodies other than the FAA to take as it has been exposed how the latter has been simply signing off too much to Boeing's trust. The 0.6 degree vs. 2.5 degree change was a big miss by the FAA as reported in the Seattle Times. I heard that the EASA was initially reluctant to certify the MAX without some changes to the MCAS but did it anyways. Indeed, they should not feel pressured to simply rubber stamp the FAA certification, which is what the FAA does when it came to certifying Airbus aircraft like the A350. If a European operator lost a MAX, questions would have been asked about how the EASA could let a flaw slip through just by blindly trusting in the FAA, which at this point is near zero given how the latter poorly handled the aftermath of the ET crash.
