The NTSB's narrative final · quoted from the NTSB record
The commercial helicopter pilot was transporting a sling load of ladders taped together and suspended by a 15-foot line. During the flight, the load shifted, and a ladder struck the tail rotor. The tail rotor separated from the helicopter, and the pilot initiated an emergency autorotation. The helicopter landed at an off-airport site and rolled onto its side. According to the operator's FAA-approved flight manual for external loads, the pilot has the sole responsibility to ensure that the load is properly rigged.
