I do hope yr post was "tongue in cheek".
Until now, I have understood that acquisition of an airworthiness certificate includes validation of the design and procedures to land and taxi to the parking point at least as often as other similar aircraft with similar pilots in similar conditions
Your points of course are valid as I hope mine are as well
All I try to do is to add balance to the discussions.
Yes it is troubling why so many MD11 end up that way. But we can't always expect to correct it via withdrawing a valid airworthiness certificate as suggested.
The final result of a sucessful outcome to the passengers and crew is also a balance between capabilities in design, operation and airmanship and we need to address the balance before calling for groundings by withdrawing a design certificate.
