2013 CHC Helicopters Eurocopter AS332 crash

On 23 August 2013, a Eurocopter AS332 Super Puma helicopter belonging to CHC Scotia crashed into the sea 2 nautical miles (3.7 km; 2.3 mi) from Sumburgh in the Shetland Islands, Scotland, while en route from the Borgsten Dolphin drilling rig. The accident killed four passengers; twelve other passengers and two crew were rescued with injuries. A further passenger committed suicide in 2017 as a result of PTSD caused by the crash. An investigation by the UK's Air Accident Investigation Branch concluded in 2016 that the accident was primarily caused by pilot error in failing to monitor instruments during approach. The public inquiry concluded in October 2020 that the crash was primarily caused by pilot error.
