What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23)Student was doing a practice auto-rotation decent to a power recovery. The engine had quit during making a touchdown auto-rotation necessary. The fact that the engine had quit was not realized until the power recovery was attempted and at that point the helicopter was not in an ideal position for the touchdown. The instructor had taken over the controls and completed the touchdown autorotation to the runway. The landing was somewhat harded than normal causing the aft skid crosstube to bend and causing a small wrinkle in the mast fairing
