Would you be able to provide me with a regulation for this?
You've suddenly put out of the air every aircraft that has not had a prop (AD Prop 1) and governors overhaul every 6 years, Every aircraft that hasn't had new hoses fitted every 5 years, every aircraft that has an engine past 12 years since overhaul, actually most aircraft maintained on schedule 5.
I think you may be confusing items listed as airworthiness limitations which are applicable to the type certificate, not maintenance schedules listed in the maintenance manual.
