What is the consequence of not maintaining proper torque on landing gear bolts?

• A. Increased braking efficiency
• B. Reduced airspeed
• C. Improper color
• D. Accelerated wear and damage

Answer: (D)

Torque provides the clamp force that keeps landing gear components firmly connected under the heavy vibration and dynamic loads of taxiing, takeoff, landing, and gear cycling. If proper torque isn’t maintained, bolts can loosen, allowing parts to shift and rub against each other. This creates fretting wear and fatigue, which over time leads to cracks, degraded joint integrity, and eventual bolt failure or damage to the mounting structure. In short, loose fasteners cause accelerated wear and damage to the gear attachment, which is why this option is the correct consequence. The other choices don’t reflect a mechanical outcome of loose fasteners—braking performance isn’t directly improved, airspeed isn’t affected by bolt torque, and color has no bearing on bolt condition.
