I see this as a move by Cessna to drive the under maintained old dogs from the sky but not so unreasonable that it will result in big problems for those who have over the years have taken the time, money and effort to look after their aircraft.
No, I believe it was the various CAAs that pushed Cessna into making SIDs.
I bet all maintenance organisations believe they are doing a good job after all they are supervised by their surveyors and their paperwork is controlled by their quality managers.
