When is a production certificate number required to be marked on an aircraft part?

A production certificate number is required to be marked on an aircraft part when it is applicable and issued for that part. This is crucial because the production certificate serves as a means of identifying parts that have been produced under an FAA-approved quality assurance system. When a production certificate is issued, it signifies that the manufacturer has complied with the required standards and that the parts can be trusted for safety and reliability.

In instances where a production certificate number is applicable, marking it on the part ensures traceability and accountability in the manufacturing process. This practice ultimately helps in maintaining safety standards and providing essential information about the part’s origin.

It’s important to note that marking the production certificate number is not required for all parts universally, only those that have been manufactured under such a certificate. This is why knowing when the production certificate is applicable is essential for maintaining compliance with FAA regulations.
