Aircraft structural parts are structure critical parts and they are exposed to various and tedious inspections from the design phase thru the end of their service life. During design phase, taking fatigue under dynamic and static loads, corrosion and aging effects into consideration, detailed calculations are performed on structural parts to be utilized with no problems during their service lives. The areas that are more prone to fail are the critical areas for these parts. The service life of a part is especially assigned according to the critical areas. These areas play the main role to assign the inspection period and the inspection types for the part as well. Critical areas may cause notch sensitivity and vary part to part but rivet/bolt hole edges, sharp edges, threads, necked down areas from elongation are the critical areas in general for a part.
