What component slows the nose gear wheels when the gear retracts?

• A. Tire Spin Down Assembly
• B. Nose Wheel Braking Unit
• C. Gear Retraction Damper
• D. Hydraulic Lock Assembly

Answer: (A)

Slowing the nose wheel before it’s stowed protects the tire and wheel assembly during retraction. When the aircraft lands, the nose wheel is often still spinning. The Tire Spin Down Assembly provides controlled drag to decelerate that wheel to a safe speed as the gear retracts, preventing high-speed rotation from being carried into the wheel well and reducing wear or damage. The other components serve different roles: the Nose Wheel Braking Unit is used for braking on the ground, not during retraction; the Gear Retraction Damper controls the rate of gear movement but doesn’t slow wheel rpm; and the Hydraulic Lock Assembly locks the gear in place once retracted.
