Narrative:
The Aérospatiale AS 350B2 Ecureuil, with registration EC-MVV, departed from La Seu d'Urgell Airport together with another similar aircraft, both belonging to the same operator, to carry out construction work on a high voltage power line in the municipality of La Vansa i Fórnols (Lleida).
The pilot flew alone but was assisted on the ground by a company operative, who had travelled to the site where they were going to work in a van.
The works consisted of placing concrete piles on a base for the subsequent installation of pylons for a high voltage power line. The operative on the ground helped to hook the piles to the helicopter line and informed the pilot when he could start the transfer for its placement. A worker from an electrical company assisted with the placement of the piles.
During the course of his work, the operator incurred a minor injury to his hand with the hook that held the concrete piles and informed the pilot that he had injured himself.
The pilot decided to take him back to the helicopter’s departure airport for medical assistance. He descended towards a nearby road and, without landing on the asphalt, picked him up and flew directly towards the aerodrome on a heading of 290º. During the flight, the helicopter crashed into a steep hillside and subsequently caught fire. There were indications
that the engine may have been affected by a loss of power.

Causes/contributing factors
The investigation has concluded that the accident occurred due to the impossibility of preparing and executing an autorotation manoeuvre after suffering a sudden loss of engine power due to the low altitude a witch the helicopter was flying.
