Abstract:  
Keywords: Rotary Flapper Peening, Pneumatic Needle Peening, Portable Tools, Repair Peening, Electronic Intensity Sensor Introduction Controlled pneumatic needle peening is often used after blending surface damage to rebuild the residual compressive layer that is removed by the blend. Controlled pneumatic needle peening can be used to peen surfaces on assembled aircraft with minimal dismantling and minimal risk of Foreign Object Debris (FOD). This technique has the advantage of a small work-head to peen difficult to reach areas while maintaining optimal stand-off distance at all times.
