A wing spar joint is provided for coupling the inboard ends of a right wing spar and a left wing spar. The wing spar joint comprises a forward fitting, an aft fitting, a spar cap a lower chord fitting and a strap member. A first plurality of fasteners secure the forward fitting and the aft fitting together through a web portion of the wing spars. A second plurality of fasteners secure the upper spar cap, the lower spar cap and the forward fitting together through upper chords of the wing spars. A third plurality of fasteners secure the lower chord fitting, the strap member and the forward fitting together through lower chords of the wing spars. The forward fitting, aft fitting, spar cap and strap member are thus secured together with the wing spars to form a rigid connecting joint at the inboard ends of the wing spars.
