OK, so what's to stop with a two man business: op 1 doing the maintenance management on aircraft A and op 2 doing the physical part and then op 2 doing the mm on aircraft B and op 1 doing the spanners bit. Seems like a real waste of time. This is all going to cost owners a hell of a lot of more money and drive GA further into the mire. It seems that creating this two tier system is another way for those who don't want to get their hands dirty to sit in office and make money. Part M seems over beaurcratic and what are facts to support this way of working: is this going to make continuing airworthiness any better, I don't think so. How many incidents are down to maintenance; usually manufacturing design problems eg valve, cylinder and casting failures.
