Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The flight instructor said that he was giving the student pilot a final instructional flight before his Federal Aviation Administration private pilot certificate check ride. The student was flying the airplane and they were cleared for the option to runway 30L; the wind was from 180 degrees at 7 knots. The flight instructor alerted the student to the left quartering tailwind for the landing. The touchdown was normal, but as the airplane slowed it began to drift left. Both pilots applied right rudder and then left rudder; however, directional control was lost and the airplane ground-looped. The left wing impacted the runway, bending and wrinkling the wing. Additionally, the aft fuselage was bent and wrinkled near the tailwheel.
