Red Tag: component is scrap or unusable Yellow Tag: component is serviceable and airworthy Green Tag: component is not airworthy but is repairable
Kinda strange that a green-tagged item is at a lower level than a yellow-tagged.
The story I heard once goes that someone had a supply of tags in a service shop during World War II. They happened to be yellow and thus a tradition was started.
