During the landing roll, the main landing gear wheels sank into soft soil/sand, and the airplane nosed over. The airplane sustained substantial damage to the rudder, left wing, and left-wing strut. The pilot reported that he had conducted multiple touch-and-go landings on parts of the lakebed prior and that the surface was softer than he anticipated during the accident landing. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N399RS](https://openairdocs.org/aircraft/N399RS), registered now, S/N 5477, built 1999 (OpenAirDocs) - Reported make and model: STODDARD HAMILTON GLASTAR - Registry model: [Salinas Ricardo GLASTAR](https://openairdocs.org/model/salinas-ricardo-glastar) (registry code 056077Q) (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: 5477 - Year built: 1999 - Airframe hours: 1310 - Engines: Lycoming IO-320-EXP 200 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, April 9, 2026 - Departed: Summer Lake, OR - Destination: Same as departure - Airport: Dry lakebed at Summer Lake. - Equipment: Electronic primary flight display, Electronic multifunction display, Angle of attack indicator ## Flight crew As NTSB recorded them.
