What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot took off from Madill, OK (IF4) heading to ardmore, OK (IF0)at appx. 1600 hrs. Shortly into the flight, the pilot observed a solid clutch light. Before he could pull the clutch circuit breaker, he heard a loud bang. At that point the pilot proceeded with autorotate and found a pasture to make a landing. He landed on the pasture, but the left side skid got caught on the soft ground and the aircraft flipped onto the pilot side. Damage was sustained on the blades and the boom assembly (blades cut the boom off the aircraft). Pilot exited the aircraft and upon inspecting the damage, noticed that the clutch belts were missing, which would've caused the clutch light to illuminate when they broke from the aircraft.
