Which item is not typically checked during a landing gear tire preflight inspection?

• A. Tread wear.
• B. Cuts.
• C. Brake fluid level.
• D. Bulges.

Answer: (C)

The essential idea is that a landing gear tire preflight is about the tire’s condition and integrity. You inspect for signs that the tire may fail in flight: tread wear to gauge remaining life and traction, cuts in the tread or sidewall that could propagate, and bulges which point to internal ply or bladder damage and can lead to sudden blowouts. These checks are all directly related to the tire itself and its ability to perform safely.

Brake fluid level, on the other hand, belongs to the brake system’s hydraulic inspection, not the tire condition. It’s checked as part of ensuring the braking system has proper fluid for operation and isn’t a function of the tire’s condition. So, the item not typically checked during a landing gear tire preflight is brake fluid level.
