Narrative:
The Bell 412 helicopter, registration EC-MTS, which was at its usual base at Ejea de los Caballeros (Zaragoza), was mobilised to assist in extinguishing a fire that had broken out at a landfill site near the same town.
The helicopter took off from the base with a total of 12 people on board, 10 brigade members and 2 pilots. It left the brigade in the northern area of the fire and proceeded to the Estanca el Gancho reservoir, to the south of the municipality of Ejea de los Caballeros, to load water.
The crew proceeded to carry out the water loading and release test, during which there were warnings of over-torque and low main rotor revolutions. After releasing the water, the warnings disappeared and the crew managed to lift the helicopter a few metres above the reservoir. Immediately afterwards, the low main rotor speed warning reappeared and the helicopter began to descend, finally impacting the water.
The helicopter floated for a few seconds, but then flipped over on its left side. The two pilots exited the aircraft under their own power without damage or injury.
