Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

According to the flight crew, the instrument approach was flown above the glideslope 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 glideslope, 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 to do so, and the airplane landed harder than expected, which resulted in a tail strike and substantial damage to the lower aft fuselage.
