On 26 August 2022, an experienced UAV pilot lost control of a DJI Mavic 3 in central Bergen and it flew at high speed towards a building. The UAV crashed through a third-floor window, slightly injuring a person inside. Why control was lost could not be established, but it appeared to be associated with a fault in the transition between two flight modes. The absence of adequate and timely technical assistance from the UAV manufacturer - which had a European import approval for it - limited the ability to establish the cause of the event, prompting three related safety recommendations.
Description
On 26 August 2022, the pilot of a DJI Mavic 3 UAV operated by TV 2 Luftfoto for proficiency prior to covering part of a triathlon competition over Bergen harbour the following day lost control of it in daytime visual conditions (VMC). After it initially performed normally and remained in sight, control of the UAV was lost. After initially moving slowly at the previously controlled height, it suddenly increased speed and tracked towards a harbourside building. The UAV crashed through a triple-glazed third floor window into a room where people were having lunch, one of whom was slightly injured. A colleague of the pilot who was simultaneously operating a DJI Air2S UAV nearby did not experience any similar loss of control.
