At 10 feet above the runway, he reduced power. The airplane landed hard on the runway and bounced. The pilot added power and the airplane veered left. The pilot applied the brakes, but the airplane continued off the left side of the runway. The airplane then impacted a fence, which resulted insubstantial damage to the left wing, right horizontal and the vertical stabilizer. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N448MT](https://openairdocs.org/aircraft/N448MT), registered now, S/N 92248, built 2020 (OpenAirDocs) - Reported make and model: CONNER MICHAEL A VANS ACFT RV-9 - Registry model: [Conner Michael A VANS ACFT RV-9](https://openairdocs.org/model/conner-michael-a-vans-acft-rv-9) (registry code 056385C) (OpenAirDocs) - Registry engine: [Lycoming YO-320 series](https://openairdocs.org/engine/lycoming-yo-320-series) (registry code 42424, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 92248 - Year built: 2020 - Airframe hours: 65 - Engines: LYCOMING YO-320 SERIES 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, December 3, 2023, 65 hours before - Departed: KHRV, Hamilton, MT - Destination: U60, Big Creek, ID - Airport: U60, Big Creek Airport, runway 19, 3,550 × 110 ft, grass/turf - Equipment: Handheld GPS ## Flight crew As NTSB recorded them.
