A method of selecting the optimum mix of resources for achieving an outcome while minimizing risk is presented. In one embodiment, the method is applied to selecting the optimum mix of manufacturing technologies and amount of use of each technology for fabricating a helicopter fuselage structure in order to minimize the recurring cost and keep the risk below a pre-selected value. The method involves selecting a plurality of resources which can be used to achieve the desired outcome. Determining an associated outcome for each resource. Establishing at least one target risk level for the desired outcome. Calculating an associated outcome and risk for a plurality of combinations of the resources at a plurality of percentage applications of each resource. Then determining an optimum mix of resources and percentage of application of each resource which maximizes the outcome while maintaining the risk below the at least one target risk level. The method can also be tailored to provide resource mixes which achieve a desired outcome over time.

A main rotor support structure assembly includes a support housing which transmits loads developed by the main rotor assembly into the airframe. Integral main rotor servo attachment lugs extend from the cylindrical body member to provide lower attachment points for the rotor servo actuators which are operable to articulate a rotor swash plate or the like. The servo attachment lugs are integrally formed as part of the cylindrical body member and spaced thereabout. A substantially L-shaped metallic insert is sandwiched and bonded within each servo attachment lug to resist axial and transverse tension of the rather high forces exerted by the rotor servo actuators.
