A folding rotor has a hub bar pivotally connected to a rotor blade. The hub bar is adapted to be connected to the rotorcraft, and includes a first locking aperture having a resilient bushing. The rotor blade includes a rotor strap that extends to a mounting element having a second locking aperture. A hinge element hingably connects the hub bar to the mounting element to enable the rotor blade to pivot with respect to the hub bar between a folded position and an extended position. The first and second locking apertures and the resilient bushing are coaxially aligned when the rotor blade is in the extended position, so that a locking pin may be positioned therethrough to lock the rotor blade in the extended position.
