Army Extends Data Warehouse for Conditioned-Based Maintenance

March 5, 2008

The system is now operational in the Logistics Support Activity organization, supporting the service's transition from reactive, fault-based maintenance to a predictive and reliability-centered approach


REDSTONE ARSENAL, AL /BUSINESS WIRE/ -- The Data Warehouse for Conditioned Based Maintenance has reached a new milestone within the U.S. Army Aviation and Missile Command (AMCOM). To better serve the needs of AMCOM, the Aviation Missile, Research and Development Engineering Center (AMRDEC) and the Program Executive Office Aviation, the Data Warehouse is now operational in the Logistics Support Activity (LOGSA), the Army's authoritative source for logistics data and logistics intelligence.

AMCOM's Conditioned Based Maintenance-Data Warehouse (CBM-DW), whose implementation is being led by defense contractor Westar Aerospace & Defense Group Inc., is the information-management side of Army Aviation's transition from its current reactive, fault-based maintenance program to a predictive and reliability-centered approach to maintenance.

The CBM-DW fuses multiple data sources containing detailed information about each aircraft by loading the disparate data and organizing it for analysis. AMRDEC and Program Management Office engineers then use the CBM-DW to correlate actual usage data with maintenance and component failure data. Acquiring vibration data and regime information (i.e., how the aircraft was flown) from onboard sensors provides insight into the condition of installed components.

Eventually, engineers will use the information in the CBM-DW to develop prognostics that predict when a component will fail based on the conditions under which it has been flown. The CBM-DW is a key enabler to linking all the data sources necessary for the implementation of CBM.

"The end goal is to eliminate unnecessary time-based inspections, decrease unscheduled, reactive maintenance, and increase unit readiness by enabling the soldier to order parts and schedule maintenance prior to component failure," said Mary Catherine Akamatsu, Director of Westar's Enterprise Life Cycle Solutions Division.

"The combination of establishing a world-class scalable data warehouse within LOGSA and deploying the first increment of the system delivery is a major step in the CBM-DW implementation strategy," Akamatsu added. "LOGSA provides enterprise-level hardware for the system's operation, expands our user base, and allows the data to be more widely available to the benefit of the Army aviation community."
