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 pilot departed from a private field and flew in the local area for approximately one hour. As he returned to the field for landing, he flew "right above stall speed" on final approach. The pilot reported that he "neglected to monitor [the airplane's] airspeed" and the airplane stalled during the landing flare. The airplane then dropped suddenly and impacted the ground just prior to the runway. The airplane sustained substantial damage to its fuselage, and no mechanical anomalies were identified.
