[mhm]

A report into a helicopter crash off Shetland in which four people died has said flight instruments were "not monitored effectively" by pilots in the moments leading up to the incident.

Four people died when the CHC Super Puma plunged into the sea on its approach to Sumburgh in August 2013.
