Analysis

The aircraft departed shannon, ireland under a two aircraft VFR flight plan and had become separated during the special VFR departure. Upon approaching frontal activity N5548X was approximately 10 miles south of the companion aircraft and elected to deviate south of a storm on his course. The pilot reported to his companion aircraft, north of the storm, that he had encountered rain and then icing conditions. The aircraft was not equipped with a heated pilot system. Rescue aircraft reported that sea fog existed in the area of the accident. The inadvertent encounter with weather was not successfully resolved and the pilot received fatal injuries upon impact with the water.
