Which statement about driving under an aircraft is correct?

• A. No vehicle/ground equipment may drive under any portion of an aircraft
• B. Vehicle/ground equipment may drive under an aircraft only while servicing
• C. They may drive under if cargo is loaded
• D. They may drive under during night if lighting is sufficient

Answer: (B)

Access under an aircraft is allowed only during servicing. The area beneath a parked plane is hazardous because engines can start unexpectedly, jet blast or prop wash can push objects or people, hot surfaces and moving components pose burn or crush risks, and certain servicing tasks (like fueling, catering, or maintenance) require access to underbelly points. When servicing is taking place, the aircraft is secured, engines are shut down, chocks are in place, and ground control coordinates movements so vehicles can safely reach the needed spots. Outside of servicing, driving under the aircraft is not permitted to protect people and equipment.

The other options don’t fit because nothing about daytime lighting or cargo loading alone changes the rule, and there isn’t a blanket allowance to drive under an aircraft—it’s restricted to authorized servicing operations.
