Probable cause

The student pilot’s improper yaw control during the landing flare and the flight instructor’s failure to take remedial action, which resulted in a hard landing.

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 reported that the student pilot began to flare for a touch-and-go landing when a wind gust yawed the airplane to the left. He added that the wind "dropped out," and the airplane landed hard with the nose low, which resulted in the nose landing gear collapsing. The airplane sustained substantial damage to the fuselage and both wings. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station located on the airport reported that, about 5 minutes before the accident, the wind was from 140° at 6 knots. The flight instructor reported that the wind was variable at 10 knots, gusting to 20 knots. The airplane landed on runway 21.
