Material Condition Tags

 

 

I was recently walking through a hangar workshop where a volunteer was reassembling a spare aircraft component that had been disassembled and cleaned. While looking over the work in progress, I noticed a similarly completed component on the bench that had a green tag attached to it. As a matter of curiosity, I enquired as to the serviceable status of the completed component, and was told by the volunteer that it was ready to be placed on the serviceable spare parts shelf. The volunteer stated that since the part was “ready to go”, he decided to mark it with a green “go” tag. When I asked him what was generally understood by the term “green tag”, he seemed hesitant. He was definitely puzzled when I told him that a “green tag” was understood to mean that a part was unserviceable, but repairable.     I then asked him if he knew what FAA Form 8130-3 was used for. Since the volunteer was not a certificated repairman or airframe or power plant mechanic, he was unfamiliar with what is known in the maintenance community as an Authorized Release (FAA Form 8130-3) Airworthiness Approval Tag. Only a part certified as airworthy (new, repaired or overhauled) can be issued a FAA Form 8130-3 for installation on an aircraft.

 

Material Condition Tags were initiated by the US Armed Forces early in the 20th Century to classify aircraft parts according to their airworthiness status. The system utilizes color codes for rapid identification of parts condition, and the current tag cards are marked with a Department of Defense (DD) number. The following Material Condition Tags are currently in use:

 

DD Form 1574               Yellow               Serviceable

DD Form 1575               Brown                Suspended

DD Form 1576               Blue                  Test / Modification

DD Form 1577-1             Red                  Unserviceable - Condemned

DD Form 1577-2             Green                Unserviceable -   Repairable

 

The term “yellow tag” is colloquially used in the aircraft industry, but it has no real formal meaning or value as to parts serviceability. Many serviceable repaired or overhauled parts are returned from Repair Stations with a yellow coded tag, but a close inspection will reveal that the tag is labeled as FAA Form 8130-3. A rejected or non-airworthy part may be “red tagged”, but will not have the FAA Form 8130-3 release. Without the FAA Form 8130-3 attached, the aircraft part is not suitable for installation. The FAA Form 8130-3 ultimately becomes part of the maintenance record of the aircraft to prove the “chain of approval” of the airworthy part.

 

FAA Form 8130-3 is a dual use form. It can be used to identify new manufactured aircraft components to be shipped both domestically and internationally (Authorized Release), and is used by FAA approved Repair Stations to certify repaired or overhauled status (Airworthiness Approval Tag). The legal document regulating the use of FAA Form 8130-3 can be found in 14 CFR FAA Order 8130.21.  

 

Our organization is highly dependent on the use of volunteer labor, but any work performed on aircraft components must conform to current FAR and FAA requirements. If in doubt, please feel free to consult your Technical Counselor or A&P to assist you in returning serviceable parts to inventory, or identifying legal components to install on our aircraft.
