Summary:

The unmanned aircraft (UA) was surveying a foreshore close to a construction site using a flight plan of pre-programmed waypoints.

During the flight the UA was affected by a change in the wind that resulted in it flying larger than normal turns. This caused the UA to overshoot its downwind waypoints and fly over the construction site. During one such overshoot the UA began to descend, as programmed, and collided with a crane on the construction site about 250 m inland.

As a result of this accident the operator made several changes to its procedures.
