What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On 10/02/2019 at approximately 1345 a CFI and student pilot rolled helicopter N4050X over during practice landings to a towable landing pad. One successful landing, with the student pilot managing the collective/pedals and the CFI managing the cyclic, immediately preceded the mishap landing. N4050X descended while backing away in a hover to set up for landing causing the right skid to make contact with the pad. Subsequent control inputs resulted in the right skid becoming a pivot point in the aft left quadrant of the towable pad. A right roll rapidly developed, a critical angle was exceeded and a dynamic rollover of the helicopter occurred. The helicopter came to rest with the right skid on the ground and the right side of the fuselage resting near the aft left corner of the landing pad.
