The nosewheel dragged through the grass about 30 ft, and the airplane then nosed over and came to rest inverted. The pilot added that this was the first time he had landed at this airstrip and that he was not aware of the hazards on the rough surface. The airplane sustained substantial damage to the rudder and wing struts. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that after the airplane touched down on the soft grass landing strip and rolled about 130 ft, the airplane's nose landing gear (NLG) impacted a soft ground depression and the NLG bent aft. The nose wheel dragged through the grass about 30 ft before the airplane nosed over and came to rest inverted. The pilot added that this was the first time he had landed at this airstrip and was not aware of the hazards on the rough surface. The airplane sustained substantial damage to the rudder and wing struts. The pilot reported no mechanical anomalies with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N777DV](https://openairdocs.org/aircraft/N777DV), registered now, S/N 105M, built 1998 (OpenAirDocs) - Reported make and model: Avid AVID MAGNUM (No Series) - Registry model: [Stucker Virgil A AVID MAGNUM](https://openairdocs.org/model/stucker-virgil-a-avid-magnum) (registry code 05605K5) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 105M - Year built: 1998 - Airframe hours: 843 - Engines: Lycoming O-320-E20 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special); Standard, Normal - Last inspection: Condition, April 24, 2019, 17 hours before - Departed: 3U2, Yellow Pine, ID - Destination: I92, Yellow Pine, ID - Airport: I92, Reed Ranch, runway 34, 2,175 × 100 ft, grass/turf - Equipment: Handheld GPS ## Flight crew As NTSB recorded them.
