He added that he took the flight controls from the student and banked left, but the airplane struck the bird. The airplane landed without further incident. The airplane sustained substantial damage to the left wing. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The Federal Aviation Administration Airport Facility Diagram page for the airport stated, in part: "Birds and wildlife on and invof [in vicinity of] arpt."
