Probable cause
The pilot's decision to take off on a soft field that exceeded the performance capabilities of the airplane, which resulted in an impact with a pole and terrain.
NTSB analysis
The pilot reported that he “failed to recon” the field he had just landed on. During his departure attempt, high density altitude and soft ground led to a longer than expected takeoff roll. While maneuvering to avoid a bank on the opposite side of a road the airplane struck a power pole resulting in substantial damage to the right wing. The pilot reported no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.
