Intermittent Fault Detection Technology Implementation and Training for Naval Surface Warfare Center Crane Division – Phase III in support of LRU/WRAs Demonstration and Evaluation for Intermittent Fault Detection (IFD) Implementation Depot Level Maintenance

NCMS Project #: 140953

Problem: Current visual inspection processes lack effectiveness and can identify only approximately 25% of total weapon system wiring problems. Intermittent faults can be found using traditional test equipment to a limited extent, but this is only possible with conventional test equipment when the intermittent faults have degraded to the extent that they are closer to becoming know faults. The DoD is currently exploring opportunities to expand its suite of depot capabilities to address the current intermittent fault-testing void.

Benefit: Through this collaboration project, NSWC Crane will develop an effective depot sustainment solution. Depot maintenance stand up is an important part of each PMAs sustainment planning process, which is mandated under USC, Title 10, Section 2464 for Core items. The implementation of this IFDIS study equates to more streamlined and productive supply-chain management of electronic systems, better buying power, more job opportunities, and more savings for the general public.

Solution/Approach: In Phase II IFD technology capability was identified in Weapon Replaceable Assemblies (WRAs), as well as the connector part numbers, suppliers, associated costs, labor and timeframes determined. The purpose of Phase III is to build upon the experiences and assess the best strategy to expand NSWC Crane capabilities with use cases based on lessons learned to develop repair procedures of intermittent fault root causes and create documentation of re-test processes.
