Electrical Bonding of Aircraft Fuel Systems
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, Electromagnetic 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.
An industry committee has reviewed documents relative to description of proper electrical bonding of aircraft fuel systems. While there are many references that include partial discussion, there has been no single document dedicated to just this subject. This AIR has addressed the subject but the previous version lacked useful detail. The intent of the current version of this AIR is to add more detail relevant to this subject. This includes expanding the outline (table of contents) and adding a higher level of detail in the way of numerical values to guide the designers with electrical bonding of aircraft fuel systems.
