CGN-42 HM and E Equipment R and M Study.

摘要

Seven distributive systems of the CGN-42 were analyzed to evaluate the Reliability and Maintainability (R/M) values specified for the major equipments of these systems. The evaluation addressed the reasonableness of the specified values from the point of view of the critical nature of the system, the reliability of the system design, and the likelihood of achieving these values in the light of Fleet operational experience with similar equipments. This report recommends changes to the existing specified values and suggests R/M values for additional equipments. It also presents a discussion of potential equipment R/M design improvement and compares the total projected corrective maintenance man-hours for manning calculations with the historical corrective maintenance man-hours experienced.
