During the landing roll, the aircraft bounced. The aircraft then touched down on the nose landing gear, rolled onto the left wing, and then slid to a stop. The airplane sustained substantial damage to the left wing and the airframe. The student reported that there were no preaccident mechanical failures or malfunctions with the aircraft that would have precluded normal operation. ## Factual narrative The student pilot in the experimental light-sport, weight shift-control aircraft reported that he experienced "unexpected high degree" aircraft banking and controllability issues during the initial climb, so he decided to land. During the landing roll, the aircraft bounced. The aircraft touched down on the nose landing gear and it rolled on to the left wing, before sliding to a stop. The airplane sustained substantial damage to the left wing and the airframe. The METAR from the airport nearest the accident site was 4 nautical miles to the west, and reported that about the time of the accident, the wind was from 340° at 4 knots. The student pilot used runway 36. The student pilot reported that there were no preaccident mechanical failures or malfunctions with the aircraft that would have precluded normal operation. ## Aircraft - Registration: [N419TN](https://openairdocs.org/aircraft/N419TN), registered now, S/N E9005 (OpenAirDocs) - Reported make and model: NORTH WING UUM INC SCOUT (X-C) - Registry model: [North Wing Uum SCOUT X-C](https://openairdocs.org/model/north-wing-uum-scout-x-c) (registry code 060006R) (OpenAirDocs) - Registry engine: [Rotax 912UL series](https://openairdocs.org/engine/rotax-912ul-series) (registry code 55571, 4 cycle) (OpenAirDocs) - Category: Weight-shift, amateur-built - Serial number: E9005 - Year built: 2010 - Airframe hours: 5 - Engines: Rotax 912 UL 80 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental light sport (Special) - Last inspection: Annual, June 20, 2019 - Departed: I72, Westfield, IN - Destination: I72, Westfield, IN - Airport: I72, Westfield, runway 36, 3,000 × 100 ft, grass/turf - Equipment: Electronic multifunction display, Airframe parachute ## Flight crew As NTSB recorded them.
