摘要： An aircraft has a vertical stabilizer having a multi-spar box and a base rib assembly secured to the multi-spar box. The base rib assembly has a pair of middle longitudinal lugs between a front and rear of the base rib assembly, a pair of front lateral lugs along the front of the base rib assembly, and a pair of rear lateral lugs along the rear of the base rib assembly. 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.

摘要： An aircraft has a vertical stabilizer with a multi-spar box and a base rib assembly secured to the multi-spar box. The base rib assembly has front longitudinal lugs, rear longitudinal lugs, and opposing middle longitudinal lugs. Front clevises corresponding to the front longitudinal lugs are secured to frame members of the fuselage of the aircraft and each has a first, second, and third mounting arms. Rear clevises corresponding to the rear longitudinal lugs are secured to frame members and each has a first, second, and third mounting arms. Middle clevises corresponding to the middle longitudinal lugs are secured to frame members and each has only first and second mounting arms. Retaining members inserted through mounting holes in each longitudinal lug and mounting holes in each corresponding clevis secures the vertical stabilizer to the fuselage.
