Narrative:
22 March 2021: UAS DJI Mavic 2 Enterprise substantially damaged when collided with a tree and crashed from an altitiude of 4 metres/12 feet at Dudley, West Midlands.

The UAS was being flown in a disused quarry and the battery charge was 35% at takeoff. After about 4 minutes the UAS automatically initiated a ‘Return-to-home’. It didn’t climb to its pre-programmed height of 80 metres (263 feet) and collided with a tree at the top of the quarry, then fell 4 metres (13 feet) to the ground".

Damage Sustained to UAS:
Per the AAIB Report "the UAS Collided with a tree and then fell 4 metres (13 feet) to the ground". It can therefore be presumed that the damage sustained was significant due to impact damage caused by collision with a tree then by the fall to the ground.

Although the AAIB does not specify the exact location of the incident, "the UAS was being flown in a disused quarry", and the nearest disused quarry to Dudley is Wren's Nest Quarry, an area of nature reserve to the northwest of Dudley in the West Midlands. The Wren's Nest is a geological Site of Special Scientific Interest in the Dudley Metropolitan Borough, north west of the town centre of Dudley, in the West Midlands of England. It is one of the most important geological locations in Britain.

It is also a Local Nature Reserve, a national nature reserve (NNR) and Scheduled Ancient Monument. The site is home to a number of species of birds and locally rare flora, such as Scabiosa columbaria (small scabious), milkwort and quaking grass. The caverns are also a nationally important hibernation site for seven different species of bat. The quarry has been disused since operations ceased in 1925.
