Abstract:  
Abstract Most of machining process that applied on one side of aircraft parts will leaves the parts in high stress state and this condition is the main causes of distortion. There are several methods that used for correction of the distortion and Corrective Shot Peening is one of them. Corrective Shot Peening is the combination of the art and the rule of thumb by applying of peening principle with S280 and /or S330 steel shot size to induce energy lock by lengthen specific area of the part and this will release the distortion. This paper will prepared the corrective peening method to overcome the distortion on 7000 series of aluminum structural parts which will impact on fit, form, function and parts service life in assembly line Key word : shot peening, correction of distortion, energy lock.
