Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The experimental amateur-built airplane sustained substantial damage when it nosed over during a forced landing on a soft field following an in-flight loss of engine power. The engine was reportedly “occasionally windmilling” during the forced landing. The local temperature was 9 degrees Celsius (C) and the dew point was 3 degrees C. The temperature and dew point were plotted on the icing chart listed in Special Airworthiness Information Bulletin CE-09-35 and their intersection fell in the “serious icing (cruise power)” temperature range.
