Grumman American Aircraft were bonded with epoxy, they are still flying after 40 years. When done properly the glue is better than bolts, nuts, and spot welds.
Not True.. I have worked on and around aircraft since 1967 and hold an A&P.. This is a current quote and what is being taught to new students..
"In practice, however, certain federal aviation regulations require substantiation that a bonded joint between any two primary structural components will carry a specified load with a maximum disbond. One solution to this lack of confidence in adhesively bonded joints has been to add metal fasteners. If an adhesively bonded joint fails, a metal fastener would continue holding the joint together.
However, data proving consistency and reliability is unavailable, and current inspection techniques are inadequate to establish confidence in adhesive bonds."
