The airplane began to ground loop and approached the edge of the runway. He applied brakes to prevent the airplane from exiting the runway into rough terrain, resulting in the airplane nosing over and becoming inverted on the runway and substantially damaging the rudder. The pilot stated there were no preimpact mechanical malfunctions or failures with the airplane. ## Factual narrative According to the pilot, he was performing a full stop landing when he encountered a quartering tailwind just prior to touchdown, resulting in a hard landing. The airplane began to "ground loop" and approached the edge of the runway. The pilot applied brakes to prevent the airplane from exiting the runway into rough terrain, resulting in the airplane nosing over and becoming inverted on the runway and substantially damaging the rudder. The pilot stated there were no malfunctions with the airplane prior to the accident. ## Aircraft - Registration: [N144LP](https://openairdocs.org/aircraft/N144LP), registered now, S/N CC11-00144, built 2010 (OpenAirDocs) - Reported make and model: Cub Crafters 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: CC11-0144 - Airframe hours: 57 - Engines: Cub Crafters CC340 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental light sport (Special) - Last inspection: Annual, September 20, 2010, 57 hours before - Departed: FLY, Falcon, CO - Destination: 9CO8, Kiowa, CO - Airport: 9CO8, Bijou Bottom Strip Airport, runway 33 ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
