The DJI Matrice 210 small unmanned aircraft (SUA)1 was performing a daylight survey exercise in light winds. After the pre-flight checks were completed, the aircraft was ascended to a height of around 5 m (~15 ft) to perform further checks. The pilot commanded small control inputs after which the aircraft became unstable and one of the motor arms broke where it attached to the aircraft. The pilot lost control and the aircraft crashed into the ground. No person was injured.

Reported Cause

Subsequent analysis of recorded data from the aircraft identified that the No 2 (front left) and No 3 (rear left) motors had stalled, leading to a loss of lift on the left side of the aircraft. It could not be established whether the motors stalled prior to or after the failure of the motor arm.
