Sequence of events

Analysis

The pilot reported that he was departing from a gravel bar and immediately after becoming airborne he initiated a left turn to follow the curve of the terrain. The wing tip impacted a stump that was about six feet tall which resulted in substantial damage to the left wing and aileron. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
