Narrative:
7 August 2020: DJI Matrice 210 V2 RTK sustained severe damage when collided at speed with a steel column at the South Arne Wellhead Platform East, Danish sector of the central North Sea. The incident was the subject of an AAIB Record-only Investigation, published on 12 November 2020, and the following is the summary from the AAIB Report:

"The UA struck a steel column shortly after takeoff in GPS mode, due to an uncommanded movement. The operator did not take manual control in time to prevent the rotors contacting the column, and the UAS fell approximately 1.5 metres to the floor, causing damage to the landing gear and rotors".

Damage Sustained to UAS
Per the AAIB Report: "damage to the landing gear and rotors".

The South Arne (Danish: Syd Arne) field is a major crude oil and associated gas production field in the Danish sector of the central North Sea. Production of oil and gas started in 1999, and peak oil and gas was in 2000. The field was initially developed through a single offshore installation (SA), two further field installations (Wellhead Platform East (WHPE) and Wellhead Platform West (WHPN)) were commissioned in 2013.
