A monolithic joint system for a fuselage to wing joint in an aircraft is provided. The joint system comprises a first vertical flange, a base plate, a second vertical flange, and damage containment features associated with at least one of these components. The first vertical flange is configured to connect to a fuselage section of the aircraft and the second vertical flange is configured to connect to a rib web of a wing, while the base plate attaches outboard wing to inboard wing box. The first vertical flange, the base plate, and the second vertical flange are formed from a continuous piece of material. The damage containment features are configured to slow propagation of an active crack tip in the joint system during operation of the aircraft. Thus, the illustrative embodiments provide a one-piece joint system for the fuselage to wing joint of an aircraft.
