Analysis

The pilot stated that he was at an enroute altitude of 1,500 ft mean sea level (500 ft above ground level), tuning a radio to the destination frequency, when he looked up there was a “drone hovering” in the path of the helicopter. He reported that it struck the main rotor disk at the 2 o’clock position and it “disintegrated.” The pilot evaluated the helicopter for vibrations or damage and elected to return to the departure airport, which was 3.5 miles away. He subsequently landed the helicopter without issue and during the postflight examination, he noted substantial damage to one of the main rotor blades. A sample was taken at the site of the main rotor blade damage and tested negative for bird DNA. A search for the unmanned aerial system was performed, however, no device was located. No Low Altitude Authorization and Notification Capability (LAANC) authorizations were requested for the area at the time of the accident. Additionally, no operational waivers had been filed with the Federal Aviation Administration for unmanned aerial system operations in the area at the time of the accident.
