'Bonding' means creating a safe electrical connection between the refuelling equipment and the aircraft to prevent sparks from static electricity during refuelling — a critical fire safety measure.\n- **Mark an external bonding point** on the nose gear (just above where the ground towing handle attaches), making it easy for ground crew to clip on the bonding cable.\n\n**Why it matters:**\nThe manufacturer had suggested putting the bonding point on the nose gear torque links, but this was awkward for regular use.
