What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Aircraft departed Logan-cache airport fro a local flight. A person in the FBO observed the left rear door open as the aircraft departed. Several minutes later the pilot was notified and acknoledged the open door. About four miles west of the airport the pilot started a descent to land in a field and close the door. The pilot and passenger felt what they thought was momentary turnulence, vibration and heard a nosie. These all alsted about five seconds. As the pilot continued the descent to the field he realized he had no anti-torque control. At approximately 400 feet AGL he entered an autorotation and landed in the field. As the aircraft was setting it rotated approximately 270 degrees to the right and rolled to the left coming to rest on the left side of the aircraft. An investigation of the tail rotor drive shaft revealed that it was sheared with indications of a stoppage originating with the tail rotor.
