Factors contributing to the accident were the stall encountered during the attempted go around and the wind gusts. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, go-around (vfr) - weather condition - gusts (contributing factor) - stall/mush - encountered, pilot in command (contributing factor) - In flight collision with terrain/water, descent - uncontrolled - aircraft control - not maintained, pilot in command (cause) - terrain condition - grass ## Analysis The airplane was substantially damaged when it impacted terrain following an attempted go around. The pilot stated that she thought she flared the aircraft a little too soon upon landing and the wind ballooned the nose up. She then applied power and the aircraft came down. A witness, who was taxiing to the runway at the time, said that he saw the accident airplane about 30 feet above the ground, wobbling its wings severely left to right, with the airplane nose high. Then the left wing dipped down, the airplane turned approximately 180 degrees, the left wing impacted the ground, and the nose crashed into the ground. The winds reported at the Butler County Regional Airport near the time of the accident were from 310 degrees at 12 knots, gusting to 16 knots. ## Factual narrative The airplane was substantially damaged when it impacted terrain following an attempted go around.
