A student pilot experienced a hard landing and subsequent aircraft overturn following a stall near the runway during a training flight with an instructor.

What happened

The incident occurred during a local training flight involving a student pilot and a certified flight instructor. Earlier that same morning, the student pilot had completed a solo flight session. After taking a short rest period, the student flew again accompanied by their instructor. Following this dual-control segment, the student pilot embarked on a second solo flight.

During the solo flight, the pilot executed two successful landings. On the third approach to the runway, the pilot initiated a go-around maneuver. During the subsequent approach attempt, the aircraft stalled at a low altitude close to the runway threshold. The stall resulted in a hard landing impact with the ground. Following the impact, the aircraft overturned.

The investigation

The investigation focused on the circumstances surrounding the stall and the subsequent hard landing. The sequence of events indicated that the pilot lost control of the aircraft's airspeed during the final approach phase. The mechanical condition of the aircraft was consistent with the damage sustained from the ground impact.

Probable cause

The student pilot's failure to maintain adequate airspeed during the approach, resulting in a stall and hard landing.
