Analysis of the Technical Issues and Certification Considerations in the Airworthiness Work of Boned Structures

The adverse properties of composite bond structure, such as complex process and environmental sensitivity, are complex and challenge the airworthiness work of it. Based on the advanced technical research in bonded structures and the successful engineering practices employed in the industry, the technical issues and certification considerations in the bonded structures’ airworthiness work are analyzed so as to provide information considered as guidelines or recommendations for the airworthiness work of boned structures. The key technical issues in bonded structures’ airworthiness work include: (1) material and process qualification and control, (2) design development and structural substantiation, (3) manufacturing implementation, (4) repair implementation, (5) service experience. The certification considerations in bonded structures’ airworthiness work include: (1) design and construction, (2) structural substantiation, (3) production, (4) continued airworthiness, (5) other elements.
