Abstract: In one embodiment, a horizontal stabilizer spar is held on the empennage of a rotorcraft by saddle fittings clamping the stabilizer spar at positions spaced apart along a longitudinal direction of the stabilizer spar. Stabilizer mounts are connected at respective ends to the saddle fittings and to vertical spars on the empennage. At least one of the stabilizer mounts is constructed to allow movement of the saddle fittings with respect to the vertical spars with at least four directions of freedom. The movable stabilizer mount is floatingly attached to a vertical spar, while the saddle fittings are connected to the respective stabilizer mounts by way of spherical bearings.
