can someone tell me when its a good time to put a plane in maintenance or tell me where the details are about A_CHECK thanks in advance

Its best to put aircraft in for maintenance before they get below 95% serviceability, as its then a 24 hour A check, and the cheapest maintenance. Below 95% it becomes a B check, which is 3 days out of service and substantially more expensive. I can't remember the details for a C check

Thank you so much for the link
