The pilot planned to arrive at his destination 10 minutes before his estimate of last light. However, after deviating around rain showers and conducting an aerial inspection of a prospecting site, the pilot's arrival was delayed until 10 minutes after last light. An approach was made to the unlit strip using the aircraft landing light for guidance. After flaring at about 15 feet agl the pilot waited for the touchdown but the aircarft stalled and struck the ground nosewheel first, collapsing the nosegear. Facilities were available at the departure aerodrome which would have allowed the pilot to obtain a weather forecast and an accurate time of last light. Despite the fact that the pilot had no night flying experience he choose to land the aircraft without requesting an emergency flare path to be laid.
