Aviation parts tag


Tagging, especially "yellow tag", is a term used in US aviation to indicate a part is serviceable and airworthy as evaluated by an FAA certified repair station. It is important to note that this term is an industry term and is not an FAA requirement or even mentioned in the Federal Aviation Regulations.
In Canada, a green tag is used for a serviceable and airworthy part, but as in the US, the presence of the tag does not guarantee that the part is legal for use in certificated aircraft.
