CDCCL ????
What is it basically all about , i went through the 100 pages EASA power point file course but i still didnt understand the rationale behind it ,all i understood is that it states the maintainance and insepctions procedures nessesary to ensure the flamability reduction means of the fuel tank are within tolerance and make sure that no source of arcing or sparks is around the tank .
in the power point file there is alot of info about it but it doesnt really explain what it is principally.
so can anyone explain it to me in a brief manner without going into the deep details , just a broad brush explanation .
thanks in advance
