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

The operator reported that while the pilot was in the airport traffic pattern, he was distracted by a radio transmission on the common traffic advisory frequency from additional landing traffic at the airport. The operator stated that the pilot continued his approach to landing, with the landing gear still retracted, having not completed the landing checklist. While on final approach, the pilot received a "terrain, terrain" alert, and perceived he was slightly low, and added power. Subsequently, the airplane landed gear up. The airplane sustained substantial damage to the horizontal stabilizer. The operator reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
