I find myself in the same position as DFC in many ways.
I maintain my own documentation, I have all the relevant manuals and I am a type rated licensed engineer.
Why should I have to pay someone to do something I have done for the last 14 years without any major problems?
I have yet to see anyone issue a scale of charges for my aircraft and I am waiting to see just what this paper chase is going to cost in reality.
The effort required to maintain it's paperwork with an aircraft only flying 100 hours a year is minimal. There are currently only 9 airframe AD's and only one is repetitive for my aircraft.
I don't mind paying if I am going to get some value for my money.
If this gets really expensive I will apply for the approval myself and contact every owner of the type in the country and do it for cost. It clearly makes more sense to do it on a type basis than have one organisation holding maintenance data for 30 types and charging accordingly!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
How is this wonderfull Part M working in practice.
Well one organisation I know of, is as we speak changing an engine because the Part M failed to tell them that it was timex and they have had another aircraft grounded for over a week because the Part M failed to complete the C of A paperwork in time.
Good job its in house otherwise the legal eagles would be making a killing already!!!!!!!!!!
