During the third landing attempt, the approach felt more stable and within several seconds of landing touchdown, an aggressive ground loop to the left developed. The right main landing gear collapsed, and the right wing sustained substantial damage. The pilot reported that there were no mechanical anomalies with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N3737R](https://openairdocs.org/aircraft/N3737R), registered now, S/N CCK-1865-0079, built 2016 (OpenAirDocs) - Reported make and model: Cub Crafters CARBON CUB EX - Registry model: [Schmidt Charles CARBON CUB EX](https://openairdocs.org/model/schmidt-charles-carbon-cub-ex) (registry code 05634Y5) (OpenAirDocs) - Registry engine: [Aerosport CC-340](https://openairdocs.org/engine/aerosport-cc-340) (registry code 01320, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: CCK-1865-0079 - Year built: 2016 - Airframe hours: 199 - Engines: ECI CC340 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Pilot - Registered owner: Pilot - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, July 9, 2020 - Departed: MVN, Mt Vernon, IL - Destination: MWA, Marion, IL - Airport: MWA, Veterans Airport, runway 11, 4,997 × 100 ft, concrete - Equipment: Electronic multifunction display, Electronic flight bag or handheld device, Onboard weather, Angle of attack indicator, ADS-B, Stall warning system ## 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
