Derco Aerospace aims at avionics intermittent faults with IFDIS fault-detection system

MILWAUKEE, 13 April 2012. The repair services segment of Derco Aerospace Inc. in Milwaukee is offering intermittent fault detection & isolation system (IFDIS) capability to help identify and isolate intermittent faults in aircraft electrical components.

Intermittent faults are among the most difficult and frustrating avionics maintenance, repair, and overhaul (MRO) issues because these problems show up every now and then, are extremely difficult to replicate and isolate, and can take long periods of work before the problems are fixed. Even after extensive maintenance, these intermittent faults often crop up again later.


"Traditionally, aircraft maintainers have scrapped electrical components where the source of intermittent faults could not be identified," explains Mike Gajewski, technical sales manager at Derco parent company Sikorsky Aerospace Services (SAS). Derco is an SAS Avionics Center of Excellence (ACoE).

"IFDIS’s capability to easily detect faulty aircraft electrical components offers our commercial and military customers a savings in both time and money while improving aircraft availability," Gajewski says. "Defective components can be repaired and expedited back into reliable service."

Derco Aerospace is an FAA-certified repair center for overhaul of aircraft components and accessories. The company has an 80,000-square-foot facility with modern testing systems, tooling, and fixtures. Derco has been supporting the C-130 transport aircraft and other transport and fighter aircraft for more than 30 years.
