A few years ago some hero decided to save some $ by not having an Airbus sim re-certified for both 340 and 330, just 330. No one told training control (or they didn't understand) so the sim was still used for 340 PCs. A bunch of guys were flying without valid ratings, had to re-do PCs.
More recently with CAD giving CX a hard time over all the licence screw ups, Manager Training asked a Capt to 'loose' his licence, so a new, valid one could be issued by CAD. Capt wasn't too keen as it would mean making a false declaration to HKG Police.
Now CX is pushing the responsibility back onto us, with reminders to check licences. It would be nice if CX could actually manage something as fundamental to an airline as air crew licencing.
