Analysis

The flight instructor reported that while on the downwind leg of the airport traffic pattern during a training flight he saw two birds in close proximity. While the student continued on the downwind leg, the flight instructor observed a black shadow in his peripheral vision and then heard a “thump.” The flight instructor informed the student of the bird strike, and with a positive exchange, took control of the airplane. He performed a normal no-flap landing and then taxied to the ramp. Postaccident examination of the airplane revealed the right wing had been substantially damaged.
