More information is coming out about the accidents involving DJI Matrice 200 series – it’s the batteries. And it’s not just the Matrice, the DJI battery failure also affecting the Inspire 2.
Hi there, the CAA has issued a new Safety Notice, which replaces this one. You can read about it here.
The New Safety Notice
The Civil Aviation Authority (CAA) has issued a new Safety Notice regarding the battery failure in the DJI Matrice 200 Series of drones. The new notice points to the batteries as the cause of the power failures in flight. It also extends restrictions to the DJI Inspires 2.
Safety Notice SN-2018/009 – Small Unmanned Aircraft DJI Battery TB50 and TB55 In-Flight Power Failures issued on 31 October 2018 replaces the SN-2018/008 – Small Unmanned Aircraft – DJI Matrice 200 Series In-Flight Power Failures which as issued on 26 October 2018. The new Safety Notice will remain in force until further notice.
DJI Battery Failure
The power issues causing the Matrice 200 series of drones is thought to be caused by the batteries. DJI is still investigating.
The TB50 and TB55 batteries are currently thought to be the cause of the problem. There is currently no evidence of a connection to the firmware version.
The TB50 batteries are used by both the Inspire 2 and Matrice 200 series. Each drone holds two batteries, which DJI has claimed provides redundancy.
Action to Take
The Safety Notice detailed the actions you are required to take it if you want to fly a Matrice or Inspire 2.
You no longer have to update the firmware on the Matrice, as the firmware version is not connected to the power failures.
Here’s a summary of the actions you need to take:
- Not fly over people.
- If you have an Operational Safety Case (OSC) then you must not:
- Fly over or within 150 m of a congested area.
- Fly within 50 m of any people.
- Fly within 50 m of any vessel, vehicle, or structure not under control of the pilot.
- Fly over or within 150 m of an open-air assembly over 1,000 people.
- Fly using Extended Visual Line of Sight (EVLOS).
As with the previous Safety Notice, if you are an Emergency Service then you need to consider this information into your decision-making process. You should also minimise flying over uninvolved people.
Keep an eye out for new information from the CAA. The limitations will be regularly reviewed by the CAA, then they get more information on the problem from DJI.
