Bonding and grounding during fueling are about controlling static electricity to prevent ignition hazards. As fuel moves through hoses and into the aircraft, friction and flow can cause charges to accumulate on the conductors and surfaces. If there’s a difference in electrical potential between the aircraft, the fueling equipment, and the surrounding environment, a spark could form and ignite fuel vapors. By bonding, you connect all conductive parts with a low-impedance path so they share the same electrical potential. By grounding, you provide a safe route for any accumulated charge to dissipate into the earth. Together, these practices keep the fueling system at equipotential and greatly reduce the risk of a static discharge igniting vapors, which is the real safety concern during fueling. This isn’t about speeding fueling or preventing corrosion; it’s about preventing dangerous sparks.
