← TechnologyWhich outcome occurs when aircraft landing gear dampers experience seal failure during touchdown?
A)Uncontrolled vertical oscillation (shimmy)✓
B)Reduced airspeed indication errors
C)Higher structural fatigue margins
D)Improved aerodynamic stall characteristics
💡 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.
