Thanks for the support
Thanks for the supporting comments cwatters and muduckace. My main concern is the certification aspects for adhesive bonded structures and repairs. I am really concerned that the current FARs do not prevent a common (the most common) cause of failure of adhesive bonded structures and yet we see more and more structural bonds being incorporated in primary and flight critical aircraft structures. Helicopter main rotor blades are almost all exclusively adhesive bonded and they are certainly flight critical.
Maybe it is time to start a new thread. This discussion is way off the original subject, but thanks for the feedback.
