A fusible plug in landing gears is a safety device designed to prevent tire explosions due to overheating. It is a small, heat-sensitive plug embedded in the wheel assembly, usually within the tire rim.

Function:
• Aircraft brakes generate a lot of heat during landing, especially in high-speed or rejected takeoff scenarios.
• If the temperature exceeds a critical limit (usually around 177–204°C or 350–400°F), the fusible plug melts.
• This allows the tire to deflate gradually rather than bursting violently, which could cause significant damage or injury.

Why is it important?
• Prevents catastrophic tire bursts on the ground.
• Reduces stress on landing gear components.
• Enhances overall aircraft safety.

Fusible plugs are commonly found in large commercial and military aircraft where braking loads are high.
