AAIB investigation to DJI Matrice 210 RTK (UAS, registration n/a) 18 July 2018

Loss of power due to erroneously high battery state of charge, Farmer’s field, Keith, Aberdeenshire, 18 July 2018.

Summary:

After about five minutes into the flight, a battery low voltage condition was detected by the UAS causing it to go into an automatic landing mode. Seventeen seconds later, while the aircraft was 25 m above the ground, it powered down and the electric motors stopped, causing it to fall to the ground. The batteries’ State of Charge (SOC) was indicating that an erroneously high amount charge remained. The cause of the erroneously high SOC is discussed in the report on the accident to DJI Matrice 210 on 4 September 2018 (see EW/G2018/09/04, AAIB Bulletin 11/2019).
