What are typical fuel leak indicators and the proper course of action if one is detected?

• A. Fuel odor, puddles, sheen on ground; isolate source, extinguish ignition sources, use spill kits, and report to maintenance.
• B. Only rely on fuel gauge readings.
• C. Ignore as long as engine runs.
• D. Splash water to locate leak.

Answer: (A)

Fuel leaks show up as a strong fuel odor, visible puddles, or a sheen on the ground, all pointing to escaping fuel that needs immediate attention. The best course of action is to isolate the source to stop more fuel from leaking, extinguish any ignition sources to reduce fire risk, use spill kits to contain and absorb the fuel and prevent spread, and report the situation to maintenance so repairs can be made and proper records kept. Relying only on fuel gauge readings isn’t enough to detect a leak, and ignoring the problem or trying to locate it by splashing water can create bigger hazards.
