Introduction
A helicopter was conducting an aerial application flight over a wooded area when a tail rotor problem occurred. The pilot reported that the problem made it necessary to extend the glide to reach an open area. The helicopter subsequently landed hard, causing the main rotor blades to strike and sever the tail boom.
Pilot Account
According to the pilot, the tail rotor issue developed during the flight. To compensate, the pilot extended the glide path to a clear area. The landing was hard, and the main rotor blades contacted the tail boom, resulting in its separation from the helicopter.
Accident Sequence
During the aerial application operation, the pilot encountered a tail rotor malfunction. An extended glide was performed to reach an open area. Upon touchdown, the impact forces caused the main rotor blades to hit the tail boom, cutting it off.
Investigation Findings
The investigation revealed that the pilot had declined to refuel the helicopter before the last takeoff. Additionally, witnesses reported that fuel was added to the tanks after the accident, prior to the arrival of the investigator.
