What happened
A student pilot had recently completed maintenance on a Cessna (type not specified in source) involving the removal of skis and the reinstallation of tundra tires. Following this procedure, the pilot added hydraulic fluid to the aircraft's brake system. After boarding the aircraft, the pilot engaged the brakes and started the engine, with no intention of departing the airport.
While the pilot was momentarily looking down at the instrument panel, the aircraft began moving downhill along the taxiway. In an attempt to stop the movement, the pilot applied full engine power to fly the aircraft. The aircraft briefly became airborne before settling into a stand of small birch trees located at the end of the taxiway. The accident resulted in structural damage to both wings and the fuselage. There were no injuries reported.
Findings
The pilot noted that a quartering tailwind contributed to the movement of the aircraft. No mechanical anomalies were identified in the aircraft prior to the accident.
