A fastening
system for attaching a component to a
fuselage structure in the interior of an aircraft is proposed, comprising several rigid retaining elements for attachment to the
fuselage structure, a position compensation device on each of the retaining elements, at least one elongated base body connectable to the retaining elements, and at least one fastening element connectable to the base body and a component to be fastened, wherein the retaining elements each have at least one structural support for connection to the
fuselage structure and a receiving holder for receiving the position compensation device, wherein the position compensation device has a first position compensation
bushing and a second position compensation
bushing, wherein the first position compensation
bushing is rotatably arranged in the receiving holder and has an eccentric first bore.wherein the second position compensation bushing is rotatably arranged in the first position compensation bushing and has an eccentric second bore, wherein the base body extends through and is held in the second opening, and wherein the base body has first connecting means along at least half of its length which are complementary to second connecting means of the at least one fastening element, such that the at least one fastening element can be connected to the base body at different positions.
