A rotor blade assembly (30) includes a flex-beam member (32) and a torque tube (40) surrounding the flex-beam member and extending partially along a rotor blade assembly length. A rotor blade (42) surrounds the flex beam member and extends from the torque tube to a blade tip. A connecting pin assembly (48) secures the rotor blade and the torque tube at the flex-beam member. The connecting pin assembly includes a first pin member (52) having a first shaft extending at least partially into the rotor blade assembly through the rotor blade from a first rotor blade side and a second pin member (64) located at a second rotor blade side. A clamping load between the first pin member and the second pin member secures the rotor blade and torque tube to the flex-beam member.
