Having established the wind was out of the southwest, he entered the traffic pattern, and confirmed the wind condition again during the downwind leg. The landing approach and touchdown were uneventful, until the airplane encountered a gust of wind that caused a change in heading. The airplane flew toward a fence, and the pilot applied engine power to correct the drift, but the airplane struck the fence and nosed over. The wings and vertical stabilizer 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: N727SS (not matched to a registry record) - Reported make and model: CUBCRAFTERS INC CC11-160 - Category: Airplane - Serial number: CC11-00200 - Year built: 2012 - Airframe hours: 893 - Engines: ECI/Titan CC340 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Primera Investments Inc - Airworthiness certificate: Special, Special light-sport (Special) - Last inspection: Annual, February 1, 2021, 79.9 hours before - Departed: LLJ, Challis, ID - Destination: Same as departure - Airport: PVT, Castle Creek Hideout, runway 7, 1,800 × 75 ft, dirt - Equipment: None ## Flight crew As NTSB recorded them.
