Fuel system mechanics practice scraping away sealant on this tool. Sealants on the bolt fasteners prevent leaks. A leak is usually the result of a sealant malfunction, said Master Sgt. Fred Adams, 168th Fuel System Maintenance shop supervisor. Most sealants on the KC-135 are original from when the aircraft was built. It wears away and must be replaced when a leak occurs. To find a leak, fuel system mechanics pressurize the fuel tank – blow it up like a balloon – and cover the surface with soapy solution, said Tech. Sgt. John Phoenix, 168th Fuel System Maintenance shop fuel system mechanic. Soap bubbles form where air is leaking out. To find the source, Airmen shove air into the tank from the outside and air bubbles form on the inside where air is leaking in. “It’s like looking for a needle in a haystack,” said Senior Airman Milford Sweat, 168th Fuel System Maintenance shop fuel system mechanic.
