During the landing roll, the airplane veered left and exited the runway, and the right wing struck the ground. When the airplane came to rest, the pilot exited the airplane and determined that there was no wind. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The pilot in the tailwheel-equipped airplane reported that, on the downwind for runway 25R, "the tower told us that there was a crosswind." During the landing roll, the airplane veered to the left and exited the left side of the runway, and the right wing collided with the ground. When the airplane came to rest, the pilot exited the airplane and determined that there was "no wind." The METAR at the accident site reported that, about the time of the accident, the wind was from 25° at 08kts. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N3276A](https://openairdocs.org/deregistered/N3276A-2020-10-10), registration cancelled 2020-10-10, S/N 25920, built 1953 (OpenAirDocs) - Reported make and model: Cessna 170 (B) - Registry model: [Cessna 170B](https://openairdocs.org/model/cessna-170b) (registry code 2072306) (OpenAirDocs) - Registry engine: [Continental C145 series](https://openairdocs.org/engine/continental-c145-series) (registry code 17012, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 25920 - Year built: 1953 - Engines: Continental C145 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Departed: OKB, Oceanside, CA - Destination: DVT, Phoenix, AZ - Flight plan: VFR - Airport: DVT, Phoenix Deer Valley, runway 25R, 4,500 × 75 ft, asphalt - Equipment: Stall warning system, Electronic flight bag or handheld device ## Flight crew As NTSB recorded them.
