The impact also led to an overtorque on the main rotor hub, which ripped away the front passenger seats.

The aircraft yawed whilst flying forward, fell and struck the ground around 50 meters from the take off point.

The BEA concluded that the landing site chosen had restricted the possibility of a safe manoeuvre for take off, and the pilot had a small safety margin with tree branches that were in shade.

They believed that the pilot may have had difficulty assessing the distance to the branches due to the shade and low light contrast.

These were in respect to training for the use of this type of aircraft in confined areas, and furthermore awareness of ageing performance of the visual system.
