The fact that the aircraft that crashed with singer Marilia Mendonça and four other people hit a power distribution tower cable, about 4 km from the runway, is not enough to conclude the accident. This is explained by the expert in risk analysis, Gustavo Cunha Mello.
“Under normal conditions, the pilot would have been able to see the tower in time to dodge the structure. It is necessary to explain the flight and aircraft conditions”, says the expert.
On Saturday (6), Companhia Energética de Minas Gerais (Cemig) reported that the singer’s plane hit a cable in an energy distribution tower of the company in Caratinga, Minas Gerais. When analyzing the situation, Cunha Mello said that the region’s airport does not have radar and that aircraft that land on the runway do not make the so-called instrument landing.
The specialist goes further and emphasizes that the landing is done visually, that is, when the pilot does not have the help of radar to help him set the landing path. For this reason, the airport in Caratinga only accepts day flights.
“The plane couldn’t be that low. The pilot would have to see the tower. What needs to be investigated is precisely the reasons why the aircraft driver did not see the structure, if there was an operational failure or some other malfunction that did not allow him to stay at the altitude he should be in order not to have a collision,” he explained.
He emphasizes that any statement at this time would be wrong and no one can be held responsible without all the causes of the accident being investigated by Organs competent bodies. But, for him, it is important to investigate the conditions that led the aircraft to fly so low, as well as to assess the possible mechanical failures in the plane.
In addition, he says, it is important to verify whether the aircraft would have coupled collision detection systems. Although not mandatory, it is very important safety equipment. “When you are close to a mountain, for example, this system warns you, triggers an alarm in the cabin to let you know that there is an object very close to the aircraft”, he explains.
The possibility that the crew may have received a high energy charge after the plane collided with the tower was a point highlighted by the specialist. According to him, it is impossible, in this case, the passengers have died because of a possible shock.
“To get a shock, the current needs to find ground. It’s impossible for you to get a shock inside the plane in a case like this. Electrons pass through the plane, but nothing happens to anyone. If the plane just hit the high voltage wire and did not get tangled up in these cables, this electrical discharge does not reach the plane or the crew,” he said.
Cunha Mello concluded by saying that if the plane had gotten tangled up in the wires and stuck to these cables, the electrical discharge would be so powerful that the aircraft would become a “fireball” and people could be charred.
