Findings · 4
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
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 student pilot of the tailwheel-equipped airplane was practicing crosswind takeoffs and landings with the flight instructor. During the second landing, a few feet above the runway on short final, the airplane's nose turned sharply to the left. The student reported that his flight instructor yelled a command, took over the controls, and added full power. The flight instructor reported that, after he took the flight controls, he attempted to go around but was unsuccessful. The airplane continued to the left through low brush and down an embankment. The tailwheel struck the edge of the embankment, and the airplane then nosed over. Both wings and wing struts sustained substantial damage. The student pilot and flight instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. An automated weather observation station located about 7 miles north of the accident airport reported that, about 8 minutes after the accident, the wind was from 310° at 11 knots. The airplane landed on runway 2.
