An aircraft joint includes a first component having an outer aerodynamic surface and an inner surface, a second component having an outer aerodynamic surface and an inner surface, and a strap assembly bridging between the inner surfaces of the first and second components. The strap assembly has a first strap part attached to the inner surface of the first component, a second strap part attached to the inner surface of the second component, and a third strap part received in the first and second strap parts in a sliding manner. The third strap part when received in the first and second strap parts constrains movement of the first component relative to the second component in a direction normal to the outer aerodynamic surfaces of the first and second components in the vicinity of the strap assembly.
