A drone pilot crashed his Phantom 4 small unmanned aircraft system into a U.S. Army helicopter in September because he was flying it out of his line of sight, the National Transportation Safety Board concluded today.
The drone pilot was a hobbyist, not a commercial operator who had passed an airman’s knowledge test to be certified by the Federal Aviation Administration. The accident occurred 2.5 miles from where he was operating the controls.
The Army pilot, whose Black Hawk helicopter was part of a presidential movement to New York for a United Nations meeting, saw the drone and tried to avoid it but didn’t have enough time.
In addition to flying beyond line of sight, the drone pilot was operating during official night conditions, in an area regularly used by helicopters and in restricted airspace. This demonstrated a “lack of understanding of the potential hazard of collision with other aircraft,” the NTSB report said.
