The left main landing gear collapsed, and the left wing tip struck the runway surface, resulting in substantial damage to the wing spar. The pilot reported that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operations. ## Aircraft - Registration: [N111XW](https://openairdocs.org/aircraft/N111XW), registered now, S/N 064, built 1997 (OpenAirDocs) - Reported make and model: Extra EA 300 (Undesignat) - Registry model: [Extra Flugzeugbau EA-300](https://openairdocs.org/model/extra-flugzeugbau-ea-300) (registry code 70218DI) (OpenAirDocs) - Registry engine: [Lycoming AEIO-540 series](https://openairdocs.org/engine/lycoming-aeio-540-series) (registry code 41568, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 064 - Year built: 1997 - Airframe hours: 1148 - Engines: Lycoming AEIO-540 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Aerobatic; Standard, Normal - Last inspection: Annual, February 6, 2020, 16 hours before - Departed: CCR, Concord, CA - Destination: CCR, Concord, CA - Airport: CCR, Buchanan Field Airport, runway 19R, 5,001 × 150 ft, concrete - Equipment: ADS-B, Stall warning system ## Flight crew As NTSB recorded them.
