Intermittent Fault Detection & Isolation System (IFDIS)

NCMS Project #: 140493

Problem: This CTMA project will expand within the “Bad Actor Laboratory” Intermittent Fault Detection & Isolation System (IFDIS) capability at Ogden Air Logistics Complex (OO-ALC) of identifying and isolating intermittent faults to the LRU currently repaired at Warner Robins Air Logistics Complex (WR-ALC).

Benefit: DoD will experience greater reliability and a dramatic reduction in NFF associated costs, by providing poor performing, high NFF “Bad Actor” LRUs to the “Bad Actor Laboratory” at OO-ALC for IFDIS testing.  This effort will also enable the repair of previously considered “un-repairable” LRUs located at WR-ALC, thus providing more assets to the warfighter to reduce weapons system downtime.  This effort will also further demonstrate and prove the use­fulness of this advanced detection and isolation equipment for other DoD weapons systems and cost reduction initiatives.  Significantly improving the reliability of the LRU will also demonstrate the overall business case for the future procurement of additional IFDISs by demonstrating a short payback period and significant return on investment (ROI).  The MLPRF IFDIS TPS procurement has already netted a 22 times ROI ($50M return) for the Government, paying for itself in less than one year.  The technology is applicable to all the services.

  • A draft specification regarding use of the intermittent fault detection system.

Solution/Approach: To accomplish this objective, the contractor will produce, test and deliver to the Government an Intermittent Fault Detection & Isolation System Test Program Set (TPS).  The project team will also generate and deliver to the government an IFDIS specification.  The TPS will utilize the IFDIS already in use at the USAF’s “Bad Actor Laboratory” at (OO-ALC delivered under a Phase III SBIR (AF01-296), “Tracking Current Flow through Units under Test.”  Some expansion of the Intermittent Fault Detector (IFD) within that IFDIS will be required to accommodate an expansion of test point coverage.

Impact on Warfighter: The IFDIS will significantly improve warfighter readiness by enabling accurate diagnosis and repair of troublesome CADCs which will result in:

  • Improved Mean Time Between Repair and increased operational time on wing.
  • Significant cost savings.
  • More effective allocation of resources.
