He elected to abort the landing and initiated a go-around. While applying right rudder, he applied full engine power and the airplane abruptly turned to the right. The airplane subsequently exited the right side of the runway and impacted terrain. The right wing was 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: [N832VS](https://openairdocs.org/aircraft/N832VS), registered now, S/N KPS 001, built 2018 (OpenAirDocs) - Reported make and model: KEVIN P STOLHAMMER KR 1 (NO SERIES) - Registry model: [Kevin P Stolhammer KR 1](https://openairdocs.org/model/kevin-p-stolhammer-kr-1) (registry code 056362U) (OpenAirDocs) - Registry engine: [Volkswagen 1700 CC](https://openairdocs.org/engine/volkswagen-1700-cc) (registry code 63510, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: KPS 001 - Year built: 2018 - Airframe hours: 3.5 - Engines: VOLKSWAGEN 1835 1700 CC 80 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, April 2, 2021 - Airport: 3W7, Grand Coulee Dam, runway 04, 4,203 × 75 ft, asphalt - Equipment: Electronic flight bag or handheld device, Handheld GPS ## Flight crew As NTSB recorded them.
