A rotor blade includes a removable blade tip section which is mounted to an outboard rotor blade section by mechanically mounting a tip spar to a main blade spar with a spar interface section which bridges a butt joint between the blade spar and the tip spar. The spar interface section is mounted within the blade spar and the tip spar with a multiple of threaded fasteners which are under shear load during rotor blade rotation.
