There are no lateral lugs between the pairs of middle lugs. A pair of middle clevises extend through corresponding apertures in an outer skin of the fuselage and are secured to one of the plurality of frame members and a plurality of retaining members are inserted through mounting holes in each middle longitudinal lug and mounting holes in each middle clevis to secure the vertical stabilizer to the aircraft fuselage.
