Abstract
A rotor blade assembly of an aircraft. The rotor blade assembly includes a blade attachment assembly rotatable with respect to a rotor hub assembly of the aircraft about a blade fold axis, and a pitch control assembly. The pitch control assembly includes a horn mount attachable to the rotor hub assembly, and a teeter bar hingedly attached to the horn mount at an interface, the interface defining a pitch control fold axis. The pitch control assembly is foldable about the pitch control fold axis when the pitch control fold axis is aligned with the blade fold axis.
