Summary:

The unmanned aircraft (UA) was completing an aerial search flight and whilst on approach to its landing site, it became unresponsive and dropped to the ground. Its motor carrier arms were damaged when the UA hit the ground. The nature of the damage suggests, although is not conclusive, that one of the arms was not correctly locked in place. In this condition it is possible the thrust from that rotor became variable rendering the UA unresponsive to control inputs.
