He corrected with right rudder, but the airplane continued left, so he applied brakes, and the airplane nosed over. 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 of the tailwheel equipped airplane reported that, after a 3-point landing, during the landing roll, the airplane veered left. He corrected with right rudder, but the airplane continued left so he applied brakes and the airplane nosed down on the runway. 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: N59DW (not matched to a registry record) - Reported make and model: Cessna 180 (J) - Category: Airplane - Serial number: 18052649 - Year built: 1975 - Airframe hours: 8041.9 - Engines: Continental O-470-S 230 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial observation, Part 91 - Operator: State Of Wisconsin - Registered owner: State Of Wisconsin - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, January 8, 2019 - Departed: DAF, Necedah, WI - Destination: C35, Reedsburg, WI - Airport: C35, Reedsburg Muni, runway 36, 4,840 × 75 ft, asphalt - Equipment: Stall warning system, Handheld GPS, ADS-B ## Flight crew As NTSB recorded them.
