Abstract:  
I was recently asked to review / develop a rotary flap peening certification program by a company in the aerospace industry. For the purpose of this article, I'll call them Company X. This company performs repair work on critical components, very few of which are shot peened by the original equipment manufacturer. The repair areas consist of slight damage that has been blended out and the areas are less than one square inch. Their need for shot peening is not vast, and the relatively small repair areas on the parts are well-suited to rotary flap peening.
