Investigator assessment
Analysis narrative
The instructor reported that during the initial climb, about 100 ft above ground level, he observed three birds on his left side, and he banked the airplane right. The trailing bird turned into the airplane, contacted the propeller, continued through the windshield, and struck the instructor in the face. After regaining control of the airplane, the instructor landed the airplane without further incident. The airplane sustained substantial damage to the windshield, and the instructor sustained minor injuries. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
