Derco Offers Intermittent Fault-detection Repairs

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.

So I am curious how does IFDIS work? Can it be used on the aircraft or is this for bench work?

To answer your question Doug, the IFDIS is optimised for intermittency detection and contains a neural-network that can test thousands of test points simultaneously and continuously. It can detect minute ohmic changes - that manifest themselves as intermittency - of less than 50 nanoseconds on every test point - simultaneously and continuously. In addition, the IFDIS will also detect shorts, opens, miswires and so on.
The technology can be used off-aircraft and on-aircraft, from flight line to OEM, and it can test everything from LRU chassis to ribbon cables, to circuit breakers, to boards, to wiring. It is in use in the US and in Europe, and to quote just one example it has saved the DoD over $40M so far on the F-16 fleet.
For more information have a look at www.usynaptics.com (IFDIS manufacturer) and www.copernicustechnology.com (Europe/Australia sales, support and services).
