I have said it before and I will say it again. Part M is the goose that lays the golden egg for maintenance organisations.
Many bleat on about how much it cost to get the approvals and all the work involved, but none of them are fessing up to the vast amount of extra work they have gained from all the lifed components or about the fact that many raped you on the grounds of getting you up to Part M standards. My own recent annual came to over 7k for replacement of components that are now lifed under Part M. Do you think the maintenance company did that work for free?
My friend just paid a certain well know organisation FOUR THOUSAND pounds in admin charges to be brought under Part M. Charged engineer rates for doing paperwork and other minor tasks that it turned out his own daughter was doing as part of her job as a summer assistant!!! It would have been cheaper to pay her to stay at home!!!
