Narrative:
23 September 2020: DJI Matrice 200 V1 UAS presumed destroyed/written off (damaged beyond repair) when crashed at Perth, Perthshire, Tayside, Scotland. The incident was the subject of an AAIB Record-only Investigation, published on 11 March 2021, and the following is the summary from the AAIB Report:

"During a training flight the UAS motors suddenly shut down and the UAS dropped into trees from a height of 390 feet. The data contained the following errors ‘Barometer Dead in Air’, ‘Not Enough Force’ and ‘ESC Error’. The insurers disposed of the UAS so no examination was possible to determine the cause".

Damage Sustained to UAS
Per the AAIB Report: The extent of damage has to be presumed, as the owner/operator disposed of the UAS before the AAIB could examine the UAS post incident. However, as the UAS fell from an altitude of 390 feet (approximately 119 metres), it can be presumed that the damage was extensive, and severe enough to warrant that the UAS was written off (damaged beyond economical repair). The fact that the owner/operator disposed of the damaged UAS very quickly after the incident would indicate that the owner/operator agreed with this conclusion!

Perth is a centrally located Scottish city, on the banks of the River Tay. It is the administrative centre of Perth and Kinross council area and is the historic county town of Perthshire.
