Abstract: A method of removing aircraft mastic includes contacting a cutting head with a body of aircraft mastic within a fuel tank of an aircraft, and vibrating the cutting head with a pneumatic vibrator to cut away the mastic without scratching the metal components to which the mastic is adhered.

Abstract: In a process for controlling a tank of an aircraft in flight configuration, provided with at least one filling fitting and at least one purge fitting, a detection gas supply is connected to at least one of the purge or filling fittings. An adaptor for measuring pressure and/or controlling the concentration of detection gas to at least one of the purge fittings is connected when the supply is connected to one of the filling fittings or to one of the filling fittings when the supply is connected to one of the purge fittings. A detection gas under pressure is injected into the tank, and at the periphery of the tank the presence of detection gas from a possible leak is detected.
