providing a hole through the sandwich structure element;
providing a bushing extending from a first bushing end to a second bushing end, the bushing having a bushing length from the first bushing end to the second bushing end, the bushing length being longer than the sandwich structure element thickness;
inserting the bushing through the hole provided through the sandwich structure element, such that the second bushing end is positioned at the second side of the sandwich structure element and the first bushing end is positioned at the first side of the sandwich structure element, and such that a first bushing part extends between the first side of the sandwich structure element and the first bushing end;
applying an elastically compressible element along the first bushing part; and
attaching a first component of the one or more components to the first bushing part, such that the elastically compressible element is arranged between a first component surface of the first component and the first side of the sandwich structure element, wherein the first component comprises a lightning receptor bracket.
