What is the primary purpose of bonding and grounding during fueling operations?

• A. To prevent corrosion of the aircraft.
• B. To ensure fueling equipment operates at maximum efficiency.
• C. To prevent static electricity buildup that could ignite vapors; and to ensure continuous electrical connection between fuel system and aircraft.
• D. To comply with environmental noise standards.

Answer: (C)

Bonding and grounding during fueling focus on safety from static electricity and vapors. As fuel flows, static charges can build up on the aircraft, hoses, and fueling equipment. A sudden discharge could ignite fuel vapors if a spark occurs. Bonding creates a low-resistance path between the aircraft and fueling gear so their electrical potentials are equal, while grounding provides a path to earth to drain away any accumulated charge. Keeping a continuous electrical connection between the fuel system and the aircraft ensures there’s no potential difference that could spark during transfer. This is the primary purpose: preventing ignition from static buildup and maintaining a safe, continuous electrical bond throughout fueling. It’s not about corrosion, efficiency, or noise standards.
