What can be used to prevent movement of fabric on the rib structure?

Using rib lacing cord is an effective method to secure the fabric to the rib structure of an aircraft. Rib lacing involves threading a strong cord, typically made of nylon or another durable material, through predefined holes on both the rib and the fabric. This process ensures that the fabric remains tightly adhered to the ribs, preventing any slack or movement that could compromise the integrity of the covering.

This technique is particularly valuable because it allows for the distribution of stresses evenly across the fabric, maintaining a taut surface that is crucial for aerodynamic performance and structural integrity. Additionally, rib lacing is essential in ensuring that the fabric remains properly aligned during flight, which is critical for safe operation.

In contrast, reinforcement tape, adhesive bonding, and heavy-duty stitching serve different purposes in the fabric covering process, such as strengthening seams or securing edges but are not specifically tailored for addressing the movement of fabric on rib structures. While they each contribute to the overall durability and functionality of the covered surface, rib lacing cord is specifically designed to keep the fabric securely attached to the ribs, making it the most suitable choice for this application.
