A hard landing could happen to any instructor. I noticed that those who taught me always had sweaty armpits. And Goat instructors are especially exposed for the valid reasons dear SQN LDR listed.
If The Goat insists on recruiting abinitio pilots with questionable motivation perhaps the airline should buy a small fleet of ATR42 that the Second Officers could flog to death all day to BAH and DMM. I imagine gear replacement on the ATR is less than the A330?? Impossible to elliminate events like this, just control the damage.
Leave the instructor alone, this is a case of bad eggs rather a sloppy cook.
