Analysis

The flight instructor stated that they were performing some touch-and-go landings at the local airport. They were on a left crosswind turning to a left downwind when they noticed 4-5 large birds circling and moving from left to right. He stated that he believed the left turn they were in would avoid the birds; however, one of the birds impacted the leading edge of the right wing. The flight characteristics and handling seemed unchanged, so they continued to fly the normal flight pattern and performed a normal landing. The bird strike resulted in substantial damage to the right-wing leading-edge spar.
