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 pilot stated that he flew to a nearby airport to practice touch-and-go takeoffs and landings. After his first touchdown, he applied power for takeoff and, as his airplane lifted off, he encountered a strong wind gust from his left side. He applied left aileron, but his right wing tip contacted the ground. The airplane cartwheeled and came to rest upright. The airplane immediately burst into flames and was consumed by the fire. The closest weather station, located 19 nautical miles from the airport, reported the wind at 280 degrees at 12 knots. The pilot reported that the wind was from the northwest at 15 knots, gusting to 20 knots.
