## Analysis

The pilot reported that while landing, a deer ran in front of the airplane from the left side. The pilot was unable to avoid the collision, and the deer struck the left wing, which resulted in substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
