A hinge rib for pivotally connecting an aerodynamic control element such as a spoiler or aileron to an aircraft structure. The hinge rib includes a first hinge rib arm having a grain oriented in a first direction and a second hinge rib arm having a grain oriented in a second direction which is not parallel with the first grain direction. The arms may be formed together from a single piece of material, or more typically they are formed separately before being attached together such that the grain of the first arm is not parallel with the grain of the second arm. |
