The pilot attempted to correct with aileron input; however, the lower left wing struck the runway. The pilot applied full power to abort the landing; however, airplane veered to the right and exited the right side of the runway. The left main landing gear struck rough terrain and the airplane subsequently nosed over and came to rest inverted, which resulted in substantial damage to the left lower wing and rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the pilot was landing the airplane on runway 02 with wind from 180° at 7 knots. ## Aircraft - Registration: [N14GC](https://openairdocs.org/aircraft/N14GC), registered now, S/N 75-6503, built 1941 (OpenAirDocs) - Reported make and model: BOEING B75N1 - Registry model: [Boeing B75N1](https://openairdocs.org/model/boeing-b75n1) (registry code 1380144) (OpenAirDocs) - Registry engine: [Lycoming R680](https://openairdocs.org/engine/lycoming-r680) (registry code 41540, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 75-6503 - Year built: 1941 - Airframe hours: 455.3 - Engines: Lycoming R680-17 225 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Jr Stearman LLC - Airworthiness certificate: Standard, Aerobatic - Last inspection: Annual, August 19, 2024, 35 hours before - Destination: Same as departure - Airport: VCB, Nut Tree, runway 02, 4,700 × 75 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.
