What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On March 19, 2011, at 1730 CST, a rotorway exec.162, experimental amateur built helicopter, N192AB, with a pilot and instructor were practicing maneuvers during an orientation flight at kplr. After performing "quick stops", the crew decided to travel to another nearby airport to complete his orientation to the helicopter. Flying at 1100' MSL approximately half way to destination, the helicopter yawed to the right as power was lost. Instructor took control and started a 180 degree auto rotation into an open field. While descending, the engine began operating for a few seconds and stopped again. Instructor landed the helicopter, but was unable to keep aircraft straight due to loss of tail rotor effectiveness. Left skid collapsed and helicopter rolled on its left side. Both crew members exited helicopter injured.
