Abstract
The construction of a stringer transition through a common base eliminates the need for plate fittings and their associated fasteners to connect opposing ends of a first stringer having a large cross-sectional area to a second stringer having a smaller cross-sectional area. A base of composite material is secured to a skin panel of an aircraft wing with the base aligned with and extending along the longitudinal length of the skin panel. The first stringer is secured to the base and the second stringer is secured to the base, with the first stringer and second stringer longitudinally aligned with the base and with a longitudinal spacing between the first stringer and the second stringer. The base connects the first stringer to the second stringer and only the base connects the first stringer to the second stringer.
