Reduction of Life Cycle Costs for a Contemporary Helicopter through Improvement of Reliability and Maintainability Parameters

Purpose The modern helicopters are designed with maximum serviceability and long life expectancy to ensure minimum life cycle cost. In this study, a framework is presented to incorporate the customer requirements on reliability and maintainability parameters into the design and development phase of a contemporary helicopter and the way how to capture operational data to establish and improve the reliability and maintainability parameters to reduce life cycle cost is discussed. Design/methodology/approach From the analysis it is established that the reliability & maintainability cost is the major contributor for the life cost. The significant reliability & maintainability parameter which influence reliability and maintainability cost is identified from analysis. The operational and design data of a contemporary helicopter is collected, compiled and analyzed to establish and improve the reliability & maintainability parameter. Findings The process depicted in the paper is followed for a contemporary helicop...
