Event Summary
A student pilot was practicing touch-and-go landings when, after landing, he applied full power to the engine. The airplane's nose veered to the left. The pilot attempted to correct with right rudder and brakes, and retarded the throttle, but the airplane departed the left side of the runway. It then entered the grassy area alongside the runway, struck a gully, and nosed over.
Aircraft and Mechanical Status
No mechanical discrepancies were reported or found with the airframe or engine. The pilot reported no issues with the airplane's systems or controls before the event.
Pilot Actions
The student pilot stated that after landing, he added full power for the next takeoff. When the nose veered left, he applied right rudder and brakes and reduced power, but was unable to prevent the excursion. The airplane left the runway surface and encountered a gully in the grass, causing it to overturn.
Conclusion
The airplane nosed over after leaving the runway and striking a gully. The pilot's attempts to control the direction with rudder and brakes were insufficient to keep the airplane on the runway.
