Analysis

The flight instructor stated that the purpose of the flight was for the sport pilot, who had not flown in several years, to accrue flight time for currency requirements. They completed flight maneuvers in the local area and returned for landing practice. During the first landing roll, the airplane drifted slightly to the right and the pilot corrected with left rudder input. The airplane veered hard left and struck a runway sign with the right wingtip. The airplane sustained substantial damage to the right wing. After the accident an examination of the tailwheel confirmed that the tailwheel was operating normally and there were no issues noted.
