The airplane nosed over, which resulted in substantial damage to the upper wing, rudder, and vertical fin. The pilot reported that there were no preimpact anomalies with the airplane that would have precluded normal operation. ## Factual narrative The pilot was wearing heavy, insulated boots during the flight. The flight was uneventful until the landing roll out. When the pilot applied rudder, the heavy boots masked the rudder's feedback. The pilot lost control of the airplane, and the airplane quickly swerved. The pilot attempted to regain control of the airplane but due to the heavy boots, he inadvertently actuated the toe brakes. The airplane nosed over resulting in substantial damage to the upper wing, rudder, and vertical fin. The pilot reported that there were no preimpact anomalies with the airplane prior to the accident. ## Aircraft - Registration: [N415WW](https://openairdocs.org/aircraft/N415WW), registered now, S/N F5C-8-126, built 2011 (OpenAirDocs) - Reported make and model: WACO CLASSIC AIRCRAFT YMF-F5C - Registry model: [Waco Classic YMF-F5C](https://openairdocs.org/model/waco-classic-ymf-f5c) (registry code 9600425) (OpenAirDocs) - Registry engine: [Jacobs R-755A2M](https://openairdocs.org/engine/jacobs-r-755a2m) (registry code 35020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: F5C-8-126 - Airframe hours: 50 - Engines: Jacobs R755A2M 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Pinnacle Waco Leasing Inc - Registered owner: Pinnacle Waco Leasing Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 20, 2011, 50 hours before - Departed: LBL, Liberal, KS - Destination: 0E0, Moriarty, NM - Airport: 0E0, Moriarty Airport, runway 26, 7,700 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
