What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot of N218GH made an approach to landing on a helicopter landing platform. Immediately after touchdown, the pilot recognized that the helicopter was left of centerline by a wider margin than was customary and announced to the passenger that he would pick the helicopter up to a hover and reposition to the right toward the centerline of the platform. The collective was increased but the helicopter developed a roll to the right that was not corrected by the pilot. The helicopter continued to roll, with the right skid as the pivot point, until rolling off of the platform and coming to rest on its side next to the platform.
