This two volume report examines the growth (or lack of it) in reliability and maintainability (R and M) characteristics of past helicopter programs and organizes the data so that they can be used as bases for predicting the R and M characteristics of future helicopter programs. Six types of R and M data are presented: (1) failure rates, (2) component-removal rates, (3) mishap rates, (4) maintenance-action rates, (5) operational availability, and (6) maintenance man-hours. Volume one also contains much data on past helicopter programs so that they will be available for use by analysts.
