Amistad, NM, USA
N721LL
BELL 206L-3
The pilot reported that the helicopter was established in cruise flight on a west-southwest course at 300 feet above ground level before the accident. The pilot stated that about 25 minutes into the flight, he observed "multiple large black birds" in the helicopter's flightpath and initiated an "immediate hard turn to the right to avoid" them. He subsequently noted an increase in main rotor speed and adjusted accordingly. The pilot rolled out on a reciprocal heading, leveled the helicopter, and began to slow down. He noticed that the descent rate was not decreasing. The helicopter touched down "hard," seemed to bounce and came to rest about 100 yards from the initial touchdown point. The pilot reported no preaccident failures or malfunctions with the helicopter that would have precluded normal operation.
On September 7, 2013, about 1530 mountain daylight time, a Bell Helicopter 206L-3, N721LL, impacted terrain after the pilot maneuvered to avoid birds during cruise flight near Amistad, New Mexico.

The intended destination was the Albuquerque International Airport (ABQ), Albuquerque, New Mexico.The pilot reported that the helicopter was established in cruise flight on a west-southwest course at 300 feet above ground level prior to the accident. The pilot and passenger were reportedly referencing a radiological monitoring system for proper operation during that timeframe. The pilot stated that about 25 minutes into the flight he observed "multiple large black birds" in the helicopter's flight path and initiated an "immediate hard turn to the right" to avoid them. He subsequently noted an increase in main rotor speed and adjusted accordingly. The pilot rolled out on a reciprocal heading, leveled the helicopter, and began to slow down. He noticed that the descent rate was not decreasing even though appropriate control inputs had been made. The helicopter touched down "hard" and seemed to bounce. The helicopter came to rest about 100 yards from the initial touchdown point. The pilot reported that there were no failures or malfunctions associated with the helicopter prior to the accident. The wind recorded at the departure airport, at 1453, was from 170 degrees at 12 knots, gusting to 21 knots. At 1553, the wind was from 170 degrees at 10 knots, gusting to 21 knots.
