ABSTRACT:
A method and apparatus for removing frozen, stuck or sealant anchored fasteners from aircraft assemblies that cannot be unscrewed by conventional screwdrivers. A pulsating force is applied through the longitudinal axis of the apparatus to the head of the fastener while simultaneously torquing the fastener alternately and sequentially in counterclockwise and clockwise directions until resistance to the removal of the fastener has been reduced to permit removal by conventional screwdriver.
