I think the comments from malcom and Just Local show that there is a need for a prefssional airworthiness management structure in place, and that was with a percieved aviation professional not somebody in their kitchen trying to understand lifing statements issued by the OEMs or perhaps it was!
I would be interested where this mis-conception that component life is an invention of EASA comes from; ever since my earlist days on the tools some aircraft components had a life, others, those defined as not airworthiness critical by the designer were put on-condition.
I notice that those complianing about cost do not mention the cost of car maintenance, significantly higher that the the rate they will pay for a licensed engineer or an airworthiness signatory. Additionally, they will be required to part with their cash before they can pick up their car, not fly off and argue the invoice when it comes through later.
