Russ brazilian authorities They will continue to work intensively this Saturday Determine the exact cause of the tragic accident antenna It happened in Vinhedo, where a plane on the local Voepass line crashed, causing All 61 people on board died. The flight took off from Cascahuel, Paraná, and was en route to São Paulo. fall suddenlycausing an uproar internationally.

Footage of the crash shows the plane starting to spin, a spiraling motion, before eventually impacting the ground inside a gated residential community. The plane flew 3,500 meters in just one minute before crashing.

Vertical and rotational descents make experts consider freezing as one of the main assumptions. possible to form There is ice on the wings This would explain the plane’s sudden vertical plunge and spin.

Dictators don’t like this

The practice of professional and critical journalism is a fundamental pillar of democracy. That’s why it bothers those who think they have the truth.

Ice formation, possible causes

Cerro Faria de SousaAviation accident criminal expert and director of the Brazilian Aviation Safety Association (Abravoo) commented Globe Ice accumulation on the wings can be a cause of accidents, especially if the de-icing system is not functioning properly.

“If I had to bet on the possible cause of the fall, I would say There is a 95% chance “That caused the fall,” he said. aircraft structure has been left intactno damage, strengthens this theory.

Nepal positioned as one of most unsafe destinations after plane crash

Additionally, another Airbus A320 pilot flying to Guarulhos on the same day reportedly observed: Cabin side windows frozensomething unusual. Ice accumulation can cause air to escape from the top of the wing, preventing the aircraft from maintaining flight, which can cause rotational motions like those recorded in accidents.

In fact, weather conditions (icing in the area where the plane lost control) were factors in the accident.

Black box recovery and historical comparison

São Paulo Public Security Minister Guilherme Derrite reported that, aircraft black box was Restored And appears to be in good condition. The device records flight data and sounds from the cockpit and is critical to better understanding accidents.

The accident continues a string of previous icing-related air tragedies. In 1994, an American Eagle ATR 72-200 crashed, and the National Transportation Safety Board attributed the cause to ice accumulation. The Federal Aviation Administration has issued operating guidance for ATRs and similar aircraft requiring pilots not to use the autopilot in icing conditions.

Similarly, in 2011, Argentina’s Sol Líneas Aéreas Flight 5428 was flying over Negros territory, heading south to Ciudad Commodore Rivadavia, and asked the control tower for permission to land, apparently because it was affected by ice. on the wing or on one of the two turboprop engines.

A breakdown in communication was also noted. The pilot did not report bad weather or call for assistance before the accident.. Ports and Airports Minister Costa Filho explained that there was no evidence that the pilot attempted to contact regional air traffic controllers.

The Voepass crash, involving a twin-engine ATR 72-500 turboprop aircraft, was the most serious since January 2023, when a similar crash in Nepal killed 72 people. In this case, the final report Attributing the accident to pilot error.

The Vignedo tragedy left a deep impression on the local community, which had to temporarily leave their homes due to the impact and subsequent fires. Local residents said no one was injured at the scene.

In the depths of southern hemisphere winter, rescuers continue to work in difficult conditions while investigations are carried out to uncover all the details of the accident.
