Insufficient electrical bonding could result in potential ignition sources inside the fuel tanks, which, in combination with flammable fuel vapours, could result in a fuel tank explosion and consequent loss of the aircraft. |\n\n![](image.001.png)  \nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n8 November 2007","sortOrder":0},{"sectionNumber":"AD/B767/232","sectionType":"part","heading":"AD/B767/232","content":"## AD/B767/232","sortOrder":1},{"sectionNumber":"Fuel Pump Housing to WingStructure Elect","sectionType":"part","heading":"Fuel Pump Housing to WingStructure Electrical Bonding","content":"## Fuel Pump Housing to Wing  \nStructure Electrical Bonding","sortOrder":2},{"sectionNumber":"13/2007","sectionType":"part","heading":"13/2007","content":"## 13/2007","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
