The 92 had a design flaw....it has been addressed.
The Check List was quite clear....but was not followed....and that is the direct cause of the Fatalities.
The 225 has a design flaw that was addressed....there was naught a crew could do. It seems perhaps just maybe....that fix did not solve the problem. Time will tell as the Investigation unfolds.
This back and forth about the 92/225 is just some much Willy Waving.
Let's deal with reality.
The Authority (Authorities) certified both.
Both Designs have serious issues that must be addressed by the Maker, the Authority, the Operator, and the Crews.
Now let's admit the existence of serious flaws in the whole of the System and start working to identify the problems so resolutions can be found.
Lives are at risk until that occurs.
