I think half the problem with maintaining aircraft nowadays, particularly in GA,is the age of the fleets. Many of these aircraft are older than the people operating and working on them. The required manuals are hard to come by or no longer updated….
The owners of these a/c need to be aware of higher workload on engineers who have to assess wear limits etc to the absolute max. rather than try to source hard to get spares….
Why are we in this game??……Must be the challenge or the love of pain

Its a big thing...when you look into it !
