You still haven't told me why Boeing is at fault. What did Boeing do to cause these two crashes?
A precautionary grounding happens when you don't know what the problem is. It may not be Boeing's fault at all. But until we can rule out the similarity between the two crashes as concerns, they should be grounded. Now that they have the CVR and FDR, they should be able to do that in weeks.
I will add that you seem to have a rather simplistic worldview where somehow blame is apportioned 100% to one party. That is not how things work in real life. In all likelihood these crashes will be a combination of things, from some minor technical defect, to amplification by some human factors consideration to a training issues to even possibly a regulatory issue. Anybody who thinks an accident will leave a single party to blame shouldn't be involved in the operation of airplanes.
This is exactly why you ground the fleet. Take the facts to date. See what mitigations can be put in that will bolster confidence. Not just in the airplanes themselves. But in the operation of them.
People keep saying they are grounded out of an abundance of caution.
You don't seem to understand what that phrase means. Or should mean to aviation professionals.
Well then shouldn't Lion Air be grounded out of an abundance of caution until their maintenance and training practices are reviewed?
Perhaps they should. But that's up to the Indonesian government. I don't live in Indonesia so the supervision of Lion Air doesn't concern me. Any more than say Air Koryo's safety record concerns me. What concerns me is whether the FAA has exercised appropriate diligence in awarding a Type Cert to Boeing when there are some stark differences in handling without augmentation. I'd like to know if that's a factor in a crash. I'd like to know if the MAX is as safe as the NG and truly flies exactly the same way. Prima facie, doesn't seem that way at the moment.
Going back to my original question. Are you going to suggest the former head of the NTSB doesn't know what he's talking about? I'd like you to stop dodging and address the comments made by those professionals in that article.
