Lead-the-Fleet (LTF): Transitioning Army Aviation Maintenance from a Time Based Maintenance System to a Usage Based System
MILITARY ACADEMY WEST POINT NY OPERATIONS RESEARCH CENTER
Pagination or Media Count:
Army helicopter system and component scheduled maintenance, overhaul, and retirement actions typically are based on calendar times and flight hours. These times are based on a composite worst-case CWC presumption of helicopter regime usage. CWC usage is derived by manufactures for each U.S. Army helicopter model to capture the most severe usage that helicopter models can ever be expected to expenence. The purpose of the Lead the Fleet LTF program is to gain better insight into the accumulated damage that each U.S. Army helicopter could experience during actual operational usage. That knowledge can then be used to more closely identif overhaul and retirement times, increase safety and operational readiness, reduce costs, and recommend condition based maintenance actions. The US Military Academys Operational Research Center of Excellence ORCEN was asked in by the Lead-the-Fleet program officer to analyze the program and make recommendations. This technical report details our findings on this research.
