What should be done following the activation of a properly operating fusible plug in a tire?

When a fusible plug in a tire is activated, it indicates that the tire has experienced excessive heat, often due to an overinflation or a malfunction in the brake system causing prolonged friction. The activation of the fusible plug signifies that the tire has reached a point where the integrity of its structure may be compromised.

In such cases, replacing the tire is essential because the heat generated can cause internal damage that is not visible from the outside, potentially leading to failure during operation. This could create serious safety risks if the tire were to blow out or degrade further while being used, as it might not provide the necessary support and stability that is required during flight.

While options such as reinflating or repairing the tire might seem feasible, they overlook the critical fact that a tire with an activated fusible plug has already shown signs of failure and cannot be trusted for safe operation. Inspecting the brake system is also important but does not address the immediate need to ensure that the tire itself is replaced to maintain safety during operations.
