Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
While on the downwind leg of the traffic pattern, the certified flight instructor (CFI) and pilot-undergoing-instruction (PUI) completed the landing checklist, but delayed the landing gear extension because they were conducting a 180-degree power-off approach. On final approach, as they were preparing to extend the landing gear, the air traffic controller told them to conduct a go-around because the landing gear was not extended. They extended the landing gear, and the CFI verified three green lights. He then requested permission to land and the tower controller cleared the airplane to land. As the airplane approached the runway, a high sink rate developed. The CFI told the PUI to add power, and the CFI simultaneously started to move the throttle control forward. The CFI said that his hand slipped past the PUI's hand, and he reached again to push the throttle forward when the airplane touched down hard on the runway. They aborted the landing, conducted a low approach to verify the position of the landing gear, and landed uneventfully. A postaccident examination revealed rib damage to the left wing. The CFI reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause Narrative
The certified flight instructor's and pilot-undergoing-instruction's improper flare, which resulted in a hard landing.
