AAIB investigation to DJI Matrice M300, (UAS registration n/a) 211121
DJI Matrice M300, motor arm folded in flight, residential area, Blacon, Chester, 21 November 2021.
Summary:
The UAS was prepared for flight to carry out an aerial search. Just after launch and prior to airborne safety checks, a “cutting noise” was heard coming from the UAS. It then lost control and dropped to the ground and was severely damaged. This was caused by one of the motor arms folding during flight which appeared not to have been correctly locked in place.
