Does the CofA renewal have to be in sync with an annual check?
I've just sold an aircraft which (for some reason in the past) had the CofA and annual out of sync with each other. This hasn't been a problem for me but the new owner is being told that it's not allowed and that the CofA must be renewed at the same time as an Annual. In this case the CofA was renewed just before the sale at the same time as a 50 hour check - but the purchaser's maintenance people have grounded him.
Where are the rules written down? And which maintenance outfit is right?
