I seem to remember when Schedule 5 first appeared that it was intended as a schedule for those aircraft whose manufacturers did not specify any maintenance schedule or the maintenance schedule was inadequate (eg. Tiger Moth).
I cannot recall (at initial release) if an owner could elect the CASA Schedule 5 in lieu of the manufacturers schedule as a simple choice - eg. it suits me better to use the CASA schedule as it will cost less etc.
Does anyone remember at what point schedule 5 could be selected in lieu of an adequate manufucturers schedule? Do you think AOPA's drive for to rid us of Australian unique ADs would extend to Schedule 5 as well?
