Hi There,
This summer I was on my vacation in Greece, and flying my Phantom 4 pro on the beach.
This was many my 100 flying over the water of any type.
I was repeating flyover, I was on 60 m of the ground/water, about 70 m of the shore and flying sideways, to the left and without any previews warning and shaking, screen just go black and warning appears "Aircraft Disconnected"

Diver found it in 7 m deep water, and two propellers (back) broken perfect on middle, and battery was next to him, out of drone, but next to him.

My reconstruction is:
Power lost without reason, then he hit the water (it is 60 m fall), props break on surface contact, also battery fall of when he hit the water.

Aircraft is sent to DJI, and they say is water damage, no warranty, and oxidized totally.
I asked my dealer to send my LOG to DJI so they can see that there is no my mistake.
And probably, after 45 days they did not successfully get flight data from craft.

Can some one analyze log file, and also I am sending screenshot from tablet after crash.
Flight data
Screenshot

Date is: august 6. 2018. last and only flight on that date.

Regards.

Ljupce,

At the end of the recorded flight data the pitch, yaw and roll data show the drone in stable flight.
It did not hit something.
The battery was quite healthy.
The data suggests a sudden loss of power as the most likely cause of the incident,

You will never get a comment from DJI .   Start a case and send the flight log in.

Sorry for such a loss of the Phantom. Must be really bad felling in that moment.
Seems everything worked normal before fall as you said. This is just the situation we all are afraid off and that's why we should never fly over the people - as you never know.

Flying over large bodies of water is always challenging and often dangerous.


Hope something can be done to resolve this in a positive finale.
