This incident is unbelievable and I am surprised by the measured responses compared to other topics on this site. This flight crew should never be allowed to fly again, what reckless action would they take if something happened in flight?
Well, as they say, this is why we pay union dues. I predict the pilots will claim they shut down the left engine and thought that was the reason for the extra thrust and steering required.
And, since no one was hurt...
They will probably receive extra 'training' in the sim on tire bursts, brake energy charts in the QRH and single engine taxi.
Then, they will get a line check and be good to go. The feds will monitor the training and go along with the remediation program.
It is nearly impossible to get fired if you are in the union but some folks occasionally succeed.
