ABSTRACT:
An aircraft structure comprising: a spar; a primary cover attached to the spar and extending on a first side of the spar; and a secondary cover positioned on a second side of the spar and partially overlapping an internal surface of the primary cover. A bracket is attached to the spar, and a spacer is provided between the secondary cover and the bracket. The spacer is sized so that the primary and secondary covers together form a substantially continuous external aerodynamic surface. The structure provides an alternative to conventional butt-strap arrangements.
