NTSB narrative
The helicopter was operating at a remote, unimproved landing zone (LZ) with a ground crew consisting of firefighters. They were conducting aerial firefighting training with an external load consisting of a 50 ft longline and a water bucket. The LZ consisted of about 2.5 ft tall prairie grass, with the tail of the helicopter going up slope. During the landing to the LZ, the tail rotor impacted a backpack on the ground. The helicopter landed upright and the pilot shutdown the helicopter. The pilot performed a self-assessment of the damage sustained to the tail rotor blades and then flew the helicopter back to the airtanker base with the ground crew onboard. The helicopter sustained substantial damage to both tail rotor blades and the tail rotor hub. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. The pilot was in radio contact with the ground crew during the training. However, during the landing, there was no communication between the ground crew and the pilot either via radio or hand signal. The orange-colored backpack was owned and was used by the ground crew. According to the operator, the pilot and the ground crew had worked together previously conducting aerial firefighting operations and the pilot had landed to the LZ several times in the past.
Probable cause
The ground crew’s failure to secure the backpack at the landing zone (LZ), that resulted in the tail rotor impacting the backpack during the landing. Contributing to the accident was the pilot’s inadequate selection of an area at the LZ, the lack of awareness of the backpack at the LZ, and the absence of communication between the pilot and the ground crew during the landing.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
