I accept your point plovett.
however I see the other side of the experience.
take my mate freddoh and his little vintage cessna 150.
it was rebuilt by a victorian LAME out of two aircraft one a crashed fuselage and one a crashed wing. the undamaged bits were married into one aircraft.
the aircraft is still the only cessna I've flown that has no need for control trim tabs it is such a straight airframe.
lived all its life in a hangar.
I don't believe it needs a sids teardown.
it is totally uneconomic to do the program and as a result a perfectly serviceable cessna will end up being scrapped.
I'd take the aeroplane out and fly it now.
I have a pretty good idea what it is like inside.
I've done work on it.
another cessna 150 I know of is sitting in a hangar somewhere in the eastern states.
it has a total of 300 hours on it.
the owner has had medical problems for decades evidently.
the sids cost will probably see it scrapped eventually.
hang your heads in shame CAsA.
