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, during a soft-field takeoff, the student kept the stick back and allowed the airplane's nose to rise. The airplane drifted to the left and he reminded the student to apply right rudder and right aileron. He added that it seemed like the student applied too much right aileron, and the right wing was close to dragging on the runway. The flight instructor prepared to take the flight controls, and the student overcorrected to the left and the left wing impacted the ground. The flight instructor took control of the airplane, reduced power, and taxied to park without further incident. The student pilot reported that, during a soft-field takeoff, about 30 to 35 knots, the airplane lifted off the ground and encountered a crosswind that rolled the airplane to the right. The right wing dragged on the ground, he rolled the airplane to the left, and the left wing then impacted the ground. The airplane sustained substantial damage to the left aileron. The school's chief flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
