Evaluation of composite components on the Bell 206L and Sikorsky S-76 helicopterA development flight testing status evaluation is presented for composite material structural components used in the Bell 206L and Sikorsky S-76 commercial helicopters, encompassing litter doors, baggage doors, forward fairings, and vertical fins. These flight tests have been conducted in various climatic conditions. The materials used in the fabrication of these components are also undergoing a separate exposure and testing program. Attention is given to results of 73,000 hrs of accumulated flight time on 206L components and 50,000 hrs on S-76 components.
