The invention relates to a method for joining two aircraft structural parts by a bolted or riveted joint and for preventing cracks at said joint. The method comprises the step (S1) of providing a first metallic aircraft structural part (100) and a second aircraft structural part (110), wherein the first aircraft structural part comprises a first joint region (101) and a second aircraft structural part comprises a second joint region (111). Furthermore, the method comprises the step (S2) of inducing compressive residual stresses in a first area (102) of the first joint region (101) for preventing cracks. Finally, the method comprises the step (S3) of fastening together the first and second aircraft structural parts (100, 110) at the first and second joint regions (101, 111) by a bolted or riveted joint (120, 210). Moreover, the invention relates to an aircraft comprising first and second aircraft structural parts.
