What identification marking is found on the selvage edge of aircraft fabric?

The identification marking you commonly find on the selvage edge of aircraft fabric is the manufacturer's logo. This logo serves as a means for identifying the fabric and its source, which is crucial for ensuring that the material meets specific quality and safety standards required in aviation.

The selvage edge is the finished edge of the fabric that helps prevent unraveling, and having the manufacturer's logo there facilitates verification of the fabric's authenticity and traceability. It's important for inspectors and technicians to be able to confirm that the material used in aircraft construction adheres to the necessary specifications and is approved for aviation use.

While certification numbers, inspection dates, and FAA-PMA stamps are essential for monitoring compliance and quality in various parts of aviation, they are not specifically found on the selvage edge of aircraft fabric. These elements are typically associated with components or parts rather than the fabric itself.
