Hello,
My Mavic 2 Pro fell to its death just over a week ago and DJI can’t explain why.
Their data “analysis” team responded so;
1. The aircraft worked under GPS mode and it responded well to the pilot’s commands;
2. Flight Time T=15:22, Relative Height H=127.1 m, Distance to Home Point D=1328.6 m, the pilot pushed the pitch stick forward, and the flight record ended when the aircraft was flying forward at 4.6 m/s;
3. Take-off point: -26.2022811 28.0604287, and the last point: -26.2014663 28.0471426.
Conclusion: Unable to figure out the cause of the accident due to the interrupted APP record.
While the report is true, there seems to be no indication of pilot error. (Of which I am certain this is not) If DJI is unable to figure out the cause of the accident and the aircraft is well within the warranty period, why am I fitting the bill??? According to DJI, the whole point of the data analysis process is to determine which party is to blame, end user or DJI. Their hardware failed to communicate the data they need.
My account is as follows; (Please excuse the long post)
The weather conditions were sunny and visibility was clear, there was no strong wind and no rain. Nearing the end of a normal condition flight, I begin recording, turn 180 degrees, hover for a moment before slowly approaching a nearby building. I descend to an an altitude of approximately 120 meters, complete a remaining battery, obstacle sensor and GPS check, when check is complete and good, I began a horizontal movement to the right keeping a safe distance from the nearby building at an approximate speed of 19km\hr.
There was no interference or loss of signal and once completely clear of the building, I proceed with 16km/hr forward movement into an open space, while tilting the gimbal slowly downward.
After a few moments into the forward movement, a loss of video and connection to my remote controller begins, I immediately release the sticks. The remote displayed no aircraft or information and no warnings as well as the controls being unresponsive. I wait for the connection to re-establish and after 15-20 seconds of waiting and still no connection, I initiate RTH but still no response or confirmation from the aircraft. I wait a few more minutes before engaging Find my Drone and proceeding to the aircrafts last known location.
After searching, I find the destroyed aircraft approximately 10-12 meters from the last known location. It had fallen through a small nearby tree before smashing into the concrete. The aircraft was on its belly with its parts scattered closely around. The camera gimbal was detached and severely damaged. The front legs were cracked and bottom sensor plate had broken clean off, propellors thrown aside, motor housings destroyed and top sensor coverings blown out. The battery was still attached but unresponsive. Later, I attempted placing a fully charged battery into the aircraft and turning it on but the aircraft was not operational and not switching on, therefore, I am unable to retrieve logs from the aircraft via Dji assistant 2.
My cached video and Flight Log verifies everything before the complete loss of signal. The gps location illustrates the craft being safely away from any structures. However, upon later inspection the last known gps point depicts the nose of the drone pointing in the opposite direction to where DJI stated the the pitch stick was being directed.
I suspect multiple hardware errors and failures, compass error, signal loss, zero warnings, video feed loss, unresponsive RC, no critical battery landing and no RTH. The aircraft is so badly damaged, it presumably fell from the last known height.
Having said all of this, pilot error HAS NOT been proven. I am a loyal DJI customer, from gimbals to drones. It would be highly appreciated for my case to be escalated and for DJI to make some attempt to honor its warranty, because if nobody is to blame according to records, it’s unacceptable to simply blame the end-user.
Thank you. |
