Derco Repair Services, an avionics element of Sikorsky Aerospace Services based in Milwaukee, has introduced an intermittent fault detection and isolation system (IFDIS) that helps pinpoint intermittent faults in electrical components.

According to a spokesman, IFDIS technology offers enhanced service capabilities and provides maintenance solutions that increase safety, reduce cost and extend the service life of existing components. “Traditionally, aircraft maintainers have scrapped electrical components where the source of intermittent faults could not be identified. IFDIS’s ability to easily detect faulty aircraft electrical components [saves time and money for] our commercial and military customers while improving aircraft availability. Defective components can be repaired and expedited back into reliable service–at a fraction of replacement costs,” he said.
