Analysis

The pilot reported that while on a pipeline aerial observation flight he encountered moderate to severe turbulence, snow showers and freezing rain. When he attempted to depart the area the aircraft began to shudder and vibrate to the extent that any further turns would have caused the aircraft to stall. The pilot elected to negotiate a 'precautionary landing' in an open area and while on final approach the left wing struck a tree. The aircraft did not experience any pre-impact malfunctions and/or failures.
