Our lot have just taken MEMS/MEDA on board, following a rather expensive incident - I don't think it was a reaction to the incident, we were already on the road to accepting MEMS/MEDA when it happened. The gods in the ivory towers have accepted it too, because they have been convinced of the potential cost saving. Time will tell!
Sad to say there are still many, many individuals who feel that punishment is the only way to reduce errors; it is changing, but slowly. I've made maintenance errors before, and so have all of you, and we'll all continue to do so. We're only human after all. It's just that sometimes you find out the error yourself, sometimes another person spots it, and occasionally it gets pointed out to everyone by the aircraft! If you get yourself an open culture on safety, everyone's a winner.
It will take time though..................
