The defining event best describes what happened. - [Landing-flare/touchdown: Abnormal runway contact](https://openairdocs.org/ntsb-events/090) (defining event); cases with it: [Airborne OUTBACK, 1 case](https://openairdocs.org/ntsb-events/090/sequence.md?model=05901TM), [All aircraft, 1,506 cases](https://openairdocs.org/ntsb-events/090/sequence.md) ## Analysis Following a cross-country flight in a weight-shift-controlled airplane, the solo student pilot approached for landing at a controlled airport. During the landing flare the aircraft began to drift to the right and the student pilot elected to perform a go-around maneuver. However, after inputting full engine throttle, the main landing gear impacted the runway about 30-45 degrees off from the runway’s centerline. The aircraft then veered off the runway and came to rest on its right side. A postaccident examination of the aircraft revealed that the wing had sustained structural damage. ## Factual narrative Following a cross-country flight in a weight-shift aircraft, the solo student pilot approached for landing at a controlled airport.
