This thesis investigates the methodology of reliability centred maintenance and applies this methodology to develop a maintenance plan for the critical load bearing structure of the Bell 47 helicopter.

A critical review of the literature on engineering reliability concepts, processes and practices outlines the critical knowledge required for the task of developing a complete reliability centred maintenance plan.

The structure analyzed is the main rotor blade and hub attachment of the Bell 47 helicopter. Helicopter aerodynamics theory is employed to determine the critical operational load cases for the system. This is followed by an analytical stress analysis which quantifies the critical operational stresses experienced by the load bearing structure. The results of this analysis, as well as material failure mechanics theory are used to predict the critical failure modes of the system.

The analysis of the system provides the necessary data to develop a complete reliability centred maintenance plan for the structure. The outcome of the thesis is a maintenance plan document intended to be included in a comprehensive maintenance manual for the entire Bell 47 rotorcraft that would allow the implementation of the most efficient and cost effective maintenance regime.
