The DJI Matrice 210 quadcopter small unmanned aircraft (SUA) 1 was being operated at night over a small industrial estate in light rain. About 20 minutes into the flight the aircraft dropped suddenly without warning from a height of 70 m (230 ft). The aircraft hit the corrugated roof of a building and was destroyed; there was some impact damage to the roof.

Reported Cause

The remains of the aircraft were sent to the manufacturer for examination. They determined that the accident was caused by a propulsion error of the No 2 motor but were unable to determine the reason for it.
