Maintainability Analysis of Major Helicopter Components.

摘要

The report examines the factors responsible for the high man-hour cost of maintaining current-inventory Army helicopters. Major components of six helicopter models were analyzed to identify the significant man-hour consumers on each aircraft. Causes for maintenance were established in terms of failure modes,maintenance frequency,and average repair time. Major component replacement tasks were structured in terms of specific time elements,and important factors affecting maintenance task performance were established. The report documents the results of three study tasks. Using data derived from the analysis, a checklist has been developed for use in maintainability analyses of future helicopter designs.
