The pilot attempted to correct to stay on the runway, however the airplane touched down and veered towards the right of the runway. The pilot attempted to regain directional control with left brake and left rudder application, but the airplane exited the right side of the runway and the nose landing gear collapsed. The airplane nosed over and came to rest inverted. The left wing and fuselage were substantially damaged. The pilot reported that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N7850K](https://openairdocs.org/deregistered/N7850K-2022-10-03), registration cancelled 2022-10-03, S/N 389, built 2007 (OpenAirDocs) - Reported make and model: JABIRU SP 250 - Registry model: [Jabiru USA Sport J250-SP](https://openairdocs.org/model/jabiru-usa-sport-j250-sp) (registry code 060001T) (OpenAirDocs) - Registry engine: [Jabiru 3300](https://openairdocs.org/engine/jabiru-3300) (registry code 34801, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 389 - Year built: 2007 - Airframe hours: 566.2 - Engines: Jabiru 3300A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 16, 2020 - Departed: WHP, Pacoima, CA - Destination: Same as departure - Airport: KTRM, Thermal, runway 35, 8,500 × 150 ft, asphalt - Equipment: Electronic primary flight display, Electronic multifunction display, ADS-B, Stall warning system ## Flight crew As NTSB recorded them.
