The paper is based on more than two decades of development and use of composite components for helicopters. First a careful definition is made of the specific kind of damages where repairability is aimed for. The criterias of repairability are described at the example of the main rotor blade. Then some repair procedures are detailed, starting with the criteria to be used to decide on repair level, showing components in particular and the aspects of design to repairability. Comparison of early and later design is used to demonstrate how improvement with respect to repairability was achieved. The concluding chapter describes service experience with the main and tail rotor blades, gained e.g. out of more than one mio. flight hours of BO 105-fleet.
