The student had completed six circuits as part of a pre-second-solo check. The student's performance was accessed as satisfactory, by his instructor, and he was cleared to complete four solo circuits. On the first solo circuit the aircraft ballooned during the landing flare. The aircraft was then observed to descend rapidly and land heavily on the main wheels after which, the nose came down starting a porposing action. The student applied full power to go-around but pitched the nose up too high (the student reported that the stall waring light and horn came on). The aircraft rolled to the left and descended impacting the ground initially with the left wing. The aircraft pitched nose first into the ground pivoting on the collapsed nosewheel in a clockwise direction whilst skidding away from the runway and coming to rest, upright, and facing the opposite direction to landing. It is probable that the student's inexperience led to control mishandling which resulted in a stall and loss of control close to the ground.
