When wiring must pass through a wheel well, how should it be protected?

• A. In conduit
• B. Left open
• C. Wrapped in duct tape
• D. Painted with primer

Answer: (A)

When wiring must pass through a wheel well, it needs solid protection against abrasion, vibration, and environmental exposure. The wheel well is a harsh area where wiring can rub against metal edges, be hit by debris, and endure heat from brakes and frequent movement of the landing gear. Running the conductor inside conduit provides a rigid, protective sleeve that shields the conductors from damage, prevents chafing, and maintains insulation and electrical integrity. It also makes inspection and servicing easier and aligns with standard aircraft wiring practices. Leaving it open, wrapping with duct tape, or painting it do not offer reliable, lasting protection for such a vulnerable route.
