The defining event best describes what happened. - [Landing-landing roll: Collision during takeoff/land](https://openairdocs.org/ntsb-events/490) (defining event); cases with it: [Cubcrafters CC11-160, 6 cases](https://openairdocs.org/ntsb-events/490/sequence.md?model=060006N), [All aircraft, 1,309 cases](https://openairdocs.org/ntsb-events/490/sequence.md) ## Analysis The pilot of the tailwheel equipped airplane reported that, he was performing practice touch-and-go takeoffs and landings on a narrow dirt airstrip. The pilot made two uneventful short-field landings and after touchdown on the third landing, while on the landing roll, the airplane began to veer to the right. The pilot added brake pressure to realign the airplane back to the center of the airstrip and away from the adjacent v-ditch. Despite the pilot’s efforts, the airplane slid into the v-ditch and nosed over coming to rest inverted. The wing strut and rudder were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N2YQ](https://openairdocs.org/aircraft/N2YQ), registered now, S/N CC11-00289, built 2013 (OpenAirDocs) - Reported make and model: CUBCRAFTERS CC11-160 - Registry model: [Cubcrafters CC11-160](https://openairdocs.org/model/cubcrafters-cc11-160) (registry code 060006N) (OpenAirDocs) - Registry engine: [Cubcrafter CC340](https://openairdocs.org/engine/cubcrafter-cc340) (registry code 18050, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: CC11-00289 - Year built: 2013 - Airframe hours: 20 - Engines: Lycoming CC340 180 hp reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental light sport (Special) - Last inspection: Annual, March 26, 2021, 20 hours before - Destination: Same as departure - Airport: U62, Mackay, runway 12R, 2,400 × 18 ft, dirt - Equipment: Stall warning system, Handheld GPS, ADS-B ## Flight crew As NTSB recorded them.
