The pilot and flight instructor attempted to correct with opposite rudder, and aileron inputs, however, the airplane ground looped to the left, and exited the left side of the runway. During the ground loop, the right wing struck the ground, which resulted in substantial damage to the lower right wing and aileron. The pilot reported there were no preaccident mechanical failures or malfunctions with the airplane that precluded normal operation. At the time of the accident, the pilot was landing on runway 22 with wind from 200° at 8 knots. ## Aircraft - Registration: [N7995](https://openairdocs.org/aircraft/N7995), registered now, S/N 75-7995, built 1943 (OpenAirDocs) - Reported make and model: Boeing-Stearman PT-17 - Registry model: [Boeing B75N1](https://openairdocs.org/model/boeing-b75n1) (registry code 1380144) (OpenAirDocs) - Registry engine: [Lycoming R680E3B](https://openairdocs.org/engine/lycoming-r680e3b) (registry code 42025, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 75-7995 - Year built: 1943 - Engines: Lycoming R-680-13 300 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: SG Squadron LLC - Airworthiness certificate: Standard, Aerobatic; Standard, Normal - Last inspection: Annual, April 10, 2024, 3 hours before - Destination: Same as departure - Airport: HCR, Heber Valley, runway 04/22, 6,898 × 75 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.
