Aircraft involved

Probable cause & findings

The flight instructor’s inadequate supervision of the student pilot, and student pilot’s improper landing flare, resulting in a hard landing.

Factual narrative

According to the flight instructor, the student pilot was practicing takeoffs and landings at the time of the accident. He reported that the student pilot completed 4 takeoffs and landings with the tendency to initiate the landing flare “a little early” and the airplane “came down a little harder” than expected. On the following landing, the instructor decided to tell the student when to start the landing flare. The approach was stabilized, but when he instructed the student to begin to flare, the student “pulled back on the yoke hard” which he had not done before. The airplane pitched “way up” and started to drift off the runway. The flight instructor assumed control, but the airplane “landed extremely hard.” The student pilot noted that he pulled back on the control wheel “too quickly and too hard.” They taxied off the runway to inspect the airplane. Observing no obvious damage, they returned to their home airport with no further difficulties. He subsequently reported the event to the flight club chief pilot and mechanic. Neither pilot reported any anomalies with respect to the airplane. A postaccident examination of the airplane revealed damage to the lower fuselage aft of the nose landing gear.
