This SAE Aerospace Information Report (AIR) is limited to the subject of aircraft fuel systems and the questions concerning the requirements for electrical bonding of the various components of the system as related to Static Electric Charges, Fault Current, Electromagnectic Interference (EMI) and Lightning Strikes (Direct and Indirect Effects). this AIR contains engineering guidelines for the design, installation, testing (measurement) and inspection of electrical bonds.The purpose of this document is to provide some guidelines for electrical bonding of structure, fluid lines and components of an aircraft fuel system. These guidelines are related to the various potential electrical charges and currents that may be applied to various portions of the system as a result of the system operation or external sources.
