The pilot reported that his approach to land towards the north-west was good, however the aircraft floated for some distance before touching down. As the aircraft landed the sun appeared from behind a cloud and the pilot lost all forward vision. Braking was applied but, as the pilot considered that the aircraft was not slowing down and he was aware that the strip end was near, he applied power to go around. The aircraft failed to become airborne and collided with a bush and a fence beyond the end of the strip. The investigation did not reveal any fault with the aircraft that could have contributed to the accident.
