Most of the rules and regulations, maintenance schedules, orders, etc are really there to protect people who are not in the aeroplane. CASA is there to protect the government from any legal challenges arising from aviation.
There are many contradictions and vaguaries. CASA seems to have set itself up as the source of all knowledge, superior to all manufacturers and engineers.
CASA has decided that the PA32 must have wing spars replaced after 11000 flying hours. Nowhere else does this happen. Piper recommends an inspection at 70,000 hours (yes seventy thousand hours), and they have a scheme for this inspection. CASA will not even accept this Piper inspection scheme.
I have serious doubts as to CASA's motivation.
