Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
The pilot was a CFI candidate and his flight instructor was preparing him to take the flight instructor practical test. He was asked to demonstrate a short field landing. The airplane crossed the threshold at 65 KIAS (knots indicated airspeed) and was flared about 60-61 KIAS. The nose "suddenly pitched down" and the airplane struck the runway "hard." The pilot added full power, retracted the flaps to 20 degrees, and rejected the landing. The airplane vibrated as it climbed 300-400 feet per minute to pattern altitude. The flight instructor assumed control of the airplane, declared an emergency, and told control tower personnel that the elevator was jammed. The instructor used power to control altitude and flew a 2-mile final approach. The engine was secured just before touchdown, and a successful landing was made. Postaccident examination disclosed the propeller had struck the runway, and the nose wheel was crooked. The nose strut was pushed back into the firewall. The elevator and elevator trim, which had been set for landing, were also jammed. No evidence of a pre-existing failure of the elevator control was found.
NTSB Probable Cause Narrative
the pilot's improper flare, and the flight instructor's inadequate supervision of the pilot.
