Matrice 200 fell out of the sky

Last week, West Midlands Police had contacted the UK’s Civil Aviation Authority (CAA) to report that one of their drones had fallen out of the sky, according to the BBC. The drone was immediately grounded and the CAA issued a warning:

“A small number of incidents have been recently reported where the aircraft has suffered a complete loss of power during flight, despite indications that there was sufficient battery time still remaining. In each case, this resulted in the aircraft falling directly to the ground due to the immediate loss of lift with the remote pilot unable to control its subsequent flight path. The small unmanned aircraft (SUA) were damaged upon impact, but the CAA has not received any reports of injuries to people or property.”

The agency Issued a safety notice and also advised on the steps to be taken, such as updating the batteries to the latest firmware And nuts to fly over any people anymore until further notice.

DJI’s official response

DJI immediately responded that the company was investigating the matter. Today they have released an official statement urging customers to fly with caution when they are using TB50 and TB55 batteries in their drones. TB55 batteries are used to power the matrice 200 drones where TB50 batteries can be found in both the Matrice 200 as well as the Inspire 2 drones.

In their statement DJI said:

“DJI is investigating reports that a small number of TB50 and TB55 batteries have shown incorrect power levels that have led to loss of power mid-flight. Flight safety and product reliability are our top priorities, and we are advising customers to fly with caution when operating their drones equipped with these batteries. In addition, DJI is working on a firmware update that will provide improvements to flight safety for the affected drones.”
