Investigator assessment
Analysis narrative
The pilot reported that, he was transporting supplies to a remote landing site and had made multiple approaches and landings. He stated that on the final approach, cloud cover had cleared and the helicopter “felt heavy.” About 25-30 ft above the ground the helicopter began to sink and he could not recover. The helicopter hit hard and tipped forward onto its nose during landing, substantially damaging the airframe and main rotors. The pilot reported that there were no preaccident malfunctions or failures with the helicopter that would have precluded normal operation.
