Analysis

The acft nosed over while taxiing for takeoff on a sand bar. The plt stated that he was demonstrating handling characteristics of the acft on sand and gravel to his passenger. The acft passed over a large hummock and settled into soft sand where it nosed over. The plt stated that during the takeoff and landings he became more agressive and less attentive. He acknowledged that he was taxiing too fast and that he purposely taxied over the hummock to use it as a reference for his ground run. This sand bar is subject to soft areas during high tides. A high flood tide had occurred earlier on the day of the accident.
