摘要

Condition-based maintenance (CBM) greatly improved reliability and readiness of Apache helicopters, according to a recent study. So the U.S. Army has decided to apply the technology to its entire fleet of Apache, Blackhawk, and Chinook choppers. Before CBM, aircraft technicians performed scheduled maintenance based only on flight hours or time intervals. They torqued fasteners to ensure proper tightness, and components were routinely replaced that still had usable life. All this added to aircraft downtime.
