I can only speak as I find, as one of the few who has the approval to sign out the aircraft that are on the EASA permit I see a lot of problems in these aircraft.
Most of the problems revolve around the landing gear with the replacement of both nose and main gear legs being an issue, the aircraft are all owned and flown by the owners who I would describe as at the upper end of the PPL skill level so I don't think that the aircraft are getting a hard time from the way that they are being flown.
The inspection regime seems to be robust enough to pick up the problems before they become a problem but I don't think that this would be the case if the aircraft was operated for training were by definition the pilots would be at the lower end of the skill level.
I have to contrast the problems that we see in these aircraft that are almost new and fly may be 50-100 hours a year with a 1980 Cessna 152 that has flown 13,000 hours+, flys 300 hours+ a year and in the past 5 years has had two nose leg seals and a few bolts and bushes in the way of maintenance, I doubt that the Cessna has cost more than £70-80 in the way of landing gear maintenance and yet this aircraft has spent its life being landed ( usually badly) by student pilots.
I am sure that the numbers will simply not stack up if using the SC for training.
