The crew was returning to the base of operations of the Helicopter Emergency Medical Service (HEMS) at the Tenerife Sur-Reina Sofía Airport. According to their testimony, they used the final approach area on taxiway T, in communication with the control tower, and proceeded to their usual parking spot on the emergency platform.
During the landing maneuver on the K-3 helipad, an intense vibration appeared in the helicopter, so the captain decided to immediately make contact with the ground, stopping on the landing surface.
Damage to the tail rotor blades, partial detachment of its gearbox and damage to the vertical stabilizer were found.
Causes/contributing factors.
The accident is thought to have occurred because the crew failed to adequately account for the strong wind while positioning the helicopter above the parking apron. This oversight was then further exacerbated by the captain taking over the flight controls with low awareness of the instability condition of the helicopter. Consequently, the helicopter overshot the helipad’s obstacle-free area, and its tail hit a tree.
