Downside with anti-icing system detected in Voepass crash probe

In line with audio recordings preserved within the so-called “black field,” the co-pilot of the doomed Voepass flight 2283 spoke of “quite a lot of ice” earlier than tragedy ensued, in keeping with a preliminary report launched Friday by Brazil’s Middle for Investigation and Prevention of Aeronautical Accidents (Cenipa), Agencia Brasil reported.

The Brazilian Air Drive’s (FAB) division highlighted that cockpit voice evaluation pointed in direction of a failure within the de-icing system that protects the plane in opposition to the formation and accumulation of ice on the wings. It was additionally decided that the “airframe de-icing” system was switched on and off a number of occasions. Nonetheless, it stays to be decided whether or not this was carried out manually by the crew or if it was a results of malfunctioning.

“There have been two occasions on the voice recorders. Within the first, the pilot feedback that there was a fault within the airframe system. In a second second, the co-pilot feedback precisely this phrase: ‘Quite a lot of ice’,” mentioned Lieutenant Colonel Paulo Mendes Fróes, who heads the Investigation Fee,

In line with Cenipa, throughout the interval by which the flight came about, there was quite a lot of humidity mixed with air temperatures beneath 0°C, which favored the incidence of Extreme Plane Ice Formation from north-central Paraná to São Paulo.

The crash occurred on August 9, within the municipality of Vinhedo (SP), and prompted the demise of the 62 folks on board, together with 4 crew members and 58 passengers.

The investigators reported that the plane was ready to fly in icy situations, with upkeep updated; and that the pilot, co-pilot, and different crew members have been certified and skilled in this sort of flight. At no time did the crew declare an emergency to the airspace management companies or to close by plane.

As well as, meteorological info was obtainable earlier than take-off and indicated extreme icing on the route. “It is very important emphasize that there isn’t any single issue for an accident, however a number of contributing elements. Within the case of PS VPB [the Voepass aircraft], the lack of management of the plane occurred throughout the flight below situations favorable to the formation of ice, however there was no declaration of emergency or report of adversarial climate situations,” Mendes Fróes defined.

Cenipa additionally said that the aircraft that crashed was registered within the Common Public Air Transport Registration Class (TPR), and was licensed and geared up with programs that allowed it to function in adversarial environmental situations, together with icing ones.

In line with Cenipa, the investigation will now observe three most important traces of motion: the human issue – which is able to assess the efficiency of the technical crew within the scenario; the fabric issue – which is able to examine the airworthiness situation, with particular consideration to the anti-icing, de-icing, and safety programs; and the operational issue – which is able to analyze the weather associated to the operational setting that will have led to the accident.

“The knowledge obtainable within the Preliminary Report could also be up to date as new factual knowledge is obtained. Our objective is to ship the ultimate report as shortly as attainable, relying on the complexity of the incident and the necessity to uncover attainable contributing elements,” Cenipa Chief Brigadier Marcelo Moreno famous.

The ATR 72 twin turboprop took off from Cascavel (PR) at 11.58 am for Guarulhos Airport. At 1.21 pm onwards, it stopped responding to calls from São Paulo Method Management (APP-SP). It hit the bottom in a residential space at 1.22 pm.

The Cenipa additionally famous that the investigation does “not search to determine guilt or legal responsibility, as offered for in § 4, artwork. 1, of Decree No. 9,540/2018, neither is it got down to show any possible reason behind an accident, however point out attainable contributing elements that permit any technical points associated to the aeronautical incidence to be elucidated.”
