Summary: Initial investigation report on deadly helicopter accident in West Alton

The National Transportation Safety Board (NTSB) has issued an initial report on a fatal helicopter accident in West Alton, Missouri. The report outlines that the helicopter hit transmission lines before crashing onto a barge, resulting in the deaths of two individuals. Technical details about the crash, including information about the aircraft's damage and plans for a thorough investigation, have been provided. The report includes three newly-released images showing the aftermath of the incident on the barge. Preliminary data from ADS-B indicates the helicopter left the Mississippi River's north bank and conducted three trips to a powerline tower on the south bank before the crash occurred at 10:59 a.m. A witness described how the helicopter's tail struck a transmission line as the pilot and a lineman on the skid attempted to attach a marker to the power lines, leading to the crash and subsequent fire. Some wreckage was recovered from the barge, while other parts were presumed to have fallen into the river. The NTSB mentioned that a video recorder from the tow vessel will undergo further examination, and underwater searches near the site will be conducted. The helicopter was said to be performing an external load flight under specific regulations during the incident, which occurred in clear weather conditions. The victims have been identified as Nicholas Fulton and Michael Curry. The NTSB anticipates that the investigation may take up to two years and will delve into various aspects, including the pilot, the aircraft, the operational setting, communications, and maintenance records.
