What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On takeoff at around 40 mph while towing a glider, the pilot suddenly realized the aircraft was settling, grass was being thrown into the air, and he could hear the prop hitting the sod runway. He immediately pulled the power back to idle and shut the engine down with the mixture control, and the aircraft settled farther and groundlooped to the right. On exiting the aircraft, the pilot noted the bolt that connected the inner attachment point of the right main gear to the bungee shock system had broken and half of the bolt was hanging from the safety cable. The glider was able to stop with no problems. There were no injuries and minor damage to the aircraft.
