The commercial pilot and one passenger were fatally injured. The other passenger had serious injuries. The flight was operated under the provision of Title 14 Code of Federal Regulations Part 135 as an on-demand air taxi flight. The Federal Aviation Administration (FAA) provided ADS-B data that showed the helicopter departed from a private wedding venue about 2145, and was enroute to DeKalb-Peachtree Airport, Atlanta, Georgia. The last recorded ADS-B point was at 2150:04, with the helicopter at 1,350 ft mean sea level (msl), travelling about 93 knots groundspeed (Figure 1). Figure 1. ADS-B with First Tree Strikes and Main Wreckage Annontated Impact signatures at the accident site were consistent with collision with tall trees and terrain in the Dawson Forest Wildlife Management Area. The first strikes were on tall trees along rising terrain following a general magnetic heading of 190°. Debris was scattered in a fan shape between 180-200°. From the first tree strike, the vertical stabilizer was located about 70 ft, the cockpit instrument panel at 173 ft, the main wreckage about 275 ft, the tail rotor gearbox at 297 ft, and the furtherest piece of wreckage, a portion of the main rotor blade was located at 472 ft. The main wreckage consisted of the pilots’ seat back, passenger cabin, main rotor mast, engine, and the beginning of the tailboom section. Portions of both main rotor blades remained attached to the main mast. The engine had fractured from the engine mounts but remained attached to the fuselage via fuel hoses (Figure 2). Figure 2. Wreckage Distribution The helicopter was recovered from the accident site and transported to a secure facility where additional documentation was performed. Examination of the airframe and engine did not detect any preimpact anomalies which would have contributed to the accident. A review of pilot information found that he completed his initial pilot testing and his line check on September 16, 2025, in both a Robinson R44 and a Robinson R66. He was graded satisfactory for all maneuvers. His pilot logbook was located at the accident site. He obtained his instrument helicopter rating on August 26, 2023, and received his commercial pilot certificate on November 10, 2023. The last entry was dated September 15, 2025. The closest aviation weather reporting facility was located about 13.8 miles to southwest of the accident site. At 2155, weather was reported to be 2 miles visibility with moderate rain and mist, and scattered clouds at 7,500 ft, with a remark for variable visibility from 1.5 miles to 3.5 miles. Modeling of weather near the accident site indicated the potential for light wind, a cloud ceiling near 200 ft above ground level (agl), and overcast clouds at 600 ft agl with rain and fog. A review of the National Weather Service (NWS)imagery showed the helicopter near an area of moderate rain at the time of the accident. Figure 3. Weather Image for 2150 with Accident Site Annotated The NWS also had a Convective Significant Meteorological Information (SIGMET) advisory issued at 2055 for an area of embedded thunderstorms moving from 220° at 15 knots with cloud tops near 40,000 ft. Figure 4. Convective SIGMET with Accident Site There was also Graphic Airman's Meteorological Information (AIRMET) advisories current for developing instrument flight rules conditions and mountain obscuration over the area.

Awaiting additional information From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
