What items are looked for during an exterior aircraft inspection?

• A. Flight controls, leaks, lights, damage
• B. Fuel quantity, cargo balance, tail number
• C. Instrument readings, avionics status, weather
• D. Engine oil level, tires, antenna condition

Answer: (A)

Exterior preflight checks focus on what you can see and test from outside the airplane to ensure the aircraft will be controllable, safe, and compliant in flight. The items you look for are flight controls, leaks, lights, and damage. Ensuring the flight control surfaces (ailerons, rudder, elevators, and associated linkages) move freely and respond properly is crucial because any binding or misalignment can prevent the airplane from responding as commanded. Checking for leaks—fuel, hydraulic, or other fluid—helps detect potential sources of in-flight loss or fire risk before takeoff. Verifying all exterior lights are present, intact, and functioning ensures you have proper visibility and signaling to others, especially in low visibility or night conditions. Finally, scanning for damage such as dents, cracks, corrosion, or compromised skin is essential because structural damage can affect aerodynamics and airworthiness.

The other options mix items that are not part of the exterior inspection focus. Fuel quantity, cargo balance, and tail number relate more to loading, weight-and-balance, or identification rather than exterior condition checks. Instrument readings, avionics status, and weather are cockpit-related preflight tasks, not exterior. Engine oil level, while important, is an internal/maintenance check rather than an exterior inspection, and while tires appear on the outside, pairing them with engine oil level makes the choice less accurate overall.
