N575Q

According to the flight crew, the instrument approach was flown above the glide slope in anticipation of mechanical turbulence. As the airplane descended through 500 ft, the pilot monitoring notified the pilot flying, that the airplane was high on the approach. The airplane continued the approach above the glide slope and the landing flare was conducted too high, which resulted in an excessive sink rate. The pilot flying attempted to arrest the sink rate but was unable, and the airplane landed harder than expected, striking the tail, which resulted in substantial damage to the lower aft fuselage.
