RMAC Analysis of CH-47 Helicopter.
Abstract
An in-depth analysis was made of the reliability, availability, maintainability and cost of the CH-47 helicopter. The study was based on available Army documentation of the A, B, and Coversions of the helicopter design; the record of component failures and removals as reflected in the Army's RAMMIT Major Item Removal Frequency (MIRF) reports; the system mission and plan for use; the Disassembly and Inspection Reports covering engineering assessment of removed failed components; and the costs in material, labor and time stemming from removal/replacement of a component. The analysis was carried out using the Army's computerized 'Analytic Methodology for System Evaluation and Control (AMSEC), together with special techniques and algorithms which were developed as required. The report provides, for the system and for each component of each version, the current RMAC assessment; a cross-comparison between the three versions; an analysis of the impact on RMAC of changes in maintenance plans, or of different costs of mission failure; and an interpretation of DIR information as it bears on RMAC.
