The helicopter reportedly crashed after colliding with high tension cables. The company that owned it, Everjets, said an investigation has been launched into the accident.
The 51-year-old pilot, identified by national newspaper Correio da Manhã as Américo Sousa, perished on Sunday lunchtime after becoming trapped inside the stricken chopper.
The helicopter had been dispatched to help tackle one of the many large blazes currently afflicting northern and central Portugal.
Portugal’s President, Marcelo Rebelo de Sousa, Home Affairs Minister Constança Urbano de Sousa, the Civil Protection Service and the local authority have all paid condolences to the tragic pilot and his family.
