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. ## Factual narrative The experimental amateur-built Rotax 447 powered airplane sustained substantial damage when it nosed over during a forced landing on a soft field following an in-flight loss of engine power.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
