AAIB investigation to DJI Phantom 3 Pro, UAS, registration n/a
Structural failure leading to loss of control, Oundle Road, Peterborough, 22 May 2018.
Summary:
The unmanned aircraft took off and reached an estimated height of 10-15 ft when an unusual noise was heard. Shortly afterwards one of the motors detached from the structure and the aircraft impacted the ground and was destroyed. The structure showed signs of multiple cracking around the motor attachment points and it is probable that these cracks joined together and resulted in the motor detaching from the structure.
