Probable cause

The student pilot's inadequate aircraft control and improper airspeed while maneuvering to land, which resulted in a stall. Contributing to the accident was the pilot's lack of experience in the make and model of the accident aircraft.

Findings · 3

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 student pilot was conducting his first solo flight in the experimental light sport, weight-shift control aircraft. He reported that he lost control of the aircraft during the initial climb after takeoff. According to a witness and the pilot's flight instructor, the pilot stalled the aircraft several times while maneuvering around the traffic pattern. During a right turn onto the final leg of the traffic pattern, the aircraft entered a steep descent and impacted the ground, which resulted in substantial damage to the airframe. The pilot stated that there were no preexisting mechanical anomalies with the aircraft. He reported 16 hours of total flight experience, which included 1 hour in the same make and model as the accident aircraft.
