The cause of the bozo's inability to execute a missed approach on the A320 and the FO's inability to remember the proper calls as the plane sunk to 38' was attributed to the lack of proper training. I don't recall that airline's entire pilot force resitting their instrument rating sims. A pilot's ratings are his own and have nothing to do with a company's AOC. If you revoke a pilot's rating by letter and then require a retest; yes. That was not done.
