On September 29, 2021, about 1400 eastern daylight time, a Hiller UH-12E helicopter, N430NR, was substantially damaged when it was involved in an accident near Millen, Georgia. The pilot sustained minor injuries. The helicopter was operated as a Title 14 Code of Federal Regulations Part 137 aerial application flight.

The pilot reported that he was enroute to his next jobsite at 800 ft above ground level and 70 kts airspeed when he heard a “pop” sound. The engine accelerated to a high RPM and the helicopter began to spin counter-clockwise at a high rate. The pilot reported that the cyclic stick would not move, pedal control inputs had no effect, and his collective control inputs were ineffective. The pilot continued his attempts to counteract the helicopter’s rotation as it descended into the ground.

The helicopter came to rest on its left side in a field. The impact sheared the right skid and the outer sections of the two main rotor blades separated. The main rotor head assembly with the remaining blade sections and one flybar paddle assembly attached sheared and came to rest approximately 45 yards aft of the fuselage. The second flybar paddle was separated from the main rotor head assembly and came to rest approximately 90 yards and at 45°from the fuselage. The tail rotor remained attached with one blade sheared approximately 8 inches from the hub.

The helicopter was retained for further examination.
