Section 19-37-4 - Bonding Prior to making any fueling connection to the aircraft, the fueling equipment shall be bonded to the aircraft by use of a cable, thus providing a conductive path to equalize potential between the fueling equipment and aircraft. The bond shall be maintained until fueling equipment connections have been removed, thus permitting the reuniting of separated charges that could be generated during the fueling operation.
(1) In addition to the above, when fueling overwing, the nozzle shall be bonded with a nozzle bond cable having a clip or plug to a metallic component of the aircraft that is metallically connected to the tank filler port. The bond connection shall be made before the filler cap is removed. If there is no plug receptacle or means for attaching a clip, the operator shall touch the filler cap with the nozzle spout before removing the cap so as to equalize the potential between the nozzle and the filler port. The spout shall be kept in contact with the filler neck until the fueling is completed.(2) When a funnel is used in aircraft fueling, it shall be kept in contact with the filler neck as well as the fueling nozzle spout or the supply container to avoid the possibility of a spark at the fill opening. Only metal funnels shall be used.(3) When a hydrant servicer or cart is used for fueling, the hydrant coupler shall be connected to the hydrant system prior to bonding the fuel equipment to the aircraft.(4) Bonding and fueling connections shall be disconnected in the reverse order of connection.(5) Conductive hose shall be used to prevent electrostatic discharge but shall not be used to accomplish required bonding.[Eff FEB 26 1993] (Auth: HRS § 261-12) (Imp: HRS § 261-12)
