Probable cause

The pilot's decision to initiate flight into freezing rain which resulted in structural icing that exceeded the ability of the aircraft to maintain flight. A factor was: improper deicing.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The aircraft was deiced with pure ethylene glycol at room temperature and then departed on an IFR flight in freezing rain and snow with a temperature/dew point of 33/31. Departure instructions were for a right turn to the north following takeoff and direct to the VOR. The aircraft was found nine hours after departing, scattered in a field, 1.5 miles north of the airport.
