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 solo student pilot reported that, while in the airport traffic pattern, the air traffic tower controller instructed her to follow a heavy jet airplane. She saw the heavy jet airplane and confirmed it with the tower controller who then cleared the pilot to land behind the heavy jet and provided a caution for wake turbulence. As she maintained a final approach to land "past the numbers" and prepared for the landing flare, the wings suddenly rolled right, and the nose dropped. She attempted to correct, but the airplane landed hard, skidded off the runway, and nosed over. The airplane sustained substantial damage to the right wing, lift struts, and empennage.

She located the heavy jet airplane and confirmed with tower she was cleared to land number two, with a caution for wake turbulence. As she maintained a final approach to land "past the numbers" and prepared for the landing flare, the wings suddenly rolled right, and the nose dropped. She attempted to correct, but the airplane landed hard, skidded off the runway, and nosed over. The airplane sustained substantial damage to the right wing, lift struts, and empennage.
