The aircraft was making a landing approach with full flap extended. The pilot said the aircraft floated for some distance, after the landing flare, before touching down about midway along the 614 metre strip. Brakes were applied but the braking action was reduced due to a mechanical impairment known to the pilot. When he realised the aircraft would overrun the strip end, the pilot said he purposely turned the aircraft to the right to prevent it from infringing a main road located a short distance ahead. The aircraft passed through a low wire fence and rolled down a steep slope before finally stopping, partially submerged, in a small dam.
