The pilot took-off with the intention of completing a circuit of the airfield. Once airborne, the pilot observed that the wind was stronger than anticipated, and he decided to abandon the circuit and land immediately in a clear field below the aircraft. During the downwind approach and when the aircraft was about 15 to 20 feet above ground level, the nose dropped suddenly. The pilot endeavoured to correct the situation by opening the throttle and attempting to raise the nose, however, this was ineffective and the aircraft collided with the ground. The pilot had recently purchased the aircraft, and although he had been advised to obtain some training before attempting to operate the aircraft he had declined to do so. The aircraft was not fitted with an air speed indicator, and assessment of speed was based on aircraft attitude in flight and speed across the ground.
