On 31 May 2013 the crew of an S76A helicopter positioning for a HEMS detail took off VFR into a dark night environment and lost control as a low level turn was initiated and did not recover. The helicopter was destroyed and the four occupants killed. The Investigation found that the crew had little relevant experience and were not operationally ready to conduct a night VFR take off into an area of total darkness. Significant deficiencies at the Operator and in respect of the effectiveness of its Regulatory oversight were identified as having been a significant context for the accident.
