Which outcome occurs when aircraft landing gear dampers experience seal failure during touchdown?

💡 Explanation

Seal failure prevents hydraulic fluid controlling the spring's **damping ratio**. This allows uncontrolled spring oscillations, called shimmy, because energy is dissipated inefficiently as the landing gear compresses and rebounds, therefore resulting in instability rather than controlled dampening.
