Possible reasons for the New York helicopter crash, according to experts

Last Thursday, a tragic accident shocked New York Bell 206 helicopter crashes in Hudson River Near Manhattan. He The bad kills the life of six people: In addition to the pilot of the same Barcelona family, five Spanish tourists (a semens manager, his wife and three children under the age of 11, 7 and 4).

Despite official research, ‘EuroNius’ has spoken to experts, and we analyzed the visible components and possibilities that led to this hazardous conclusion of the helicopter.

Face -E -Face Witnesses

Witnesses provide important traces of what happened. Bruce wall He said the helicopter released by the tail and Helix had seen the “crash” in the air. He still revealed that “the plane continued to fall without falling,” which indicates a severe structure failure.

For its part, Leslie Kamacho, the receptionist from the nearest restaurantHe noticed how the helicopter’s impact had “spinned” without “control, and said that” a lot of smoke was revealed “and that the plane” rotated very fast “before crashed into violence against the water.

How was Bell 206 L helicopter

• Ground load: 3.7 kg/m in the cabin, 4.2 kg/m in the luggage box

From the ATS-B exchange we can find on the airway, the plane was made without problems at a standard height across the Hudson River. If we see the historic plane, it is a Daily trip.

Preliminary hypothesis

Michael Roth, Managing Director of New York Helicopter ToursFeeling two reasons for:

• Impact with a bird during the plane
• Mechanical failure in helicopter blades

It should be noted that these helicopters are Bell 206 Single -EngineWith the ability of seven persons, they need severe maintenance and can be subjected to mechanical failures if appropriate reviews are made.

‘Eurneus’ Jessas Antonio Maturana de La Torre with over 35 years of experience Civil Guard helicopter mechanic He has told us two possible scenes to explain the loss of the main rotor and the tail damage.

It has also made it clear that they are the principles based on potential mechanical problems that can make that decision, and we should do Wait for the analysis of residues to confirm these principles Or if there is any additional external element in the equation.

The First theoryPerhaps less, this is a fatigue problem with the axis of the main rotor, which sits the same due to a malfunction or maintenance, which falls directly into the river as seen in the following video.

If this can occur Standard problem or rotor axis Or the clamps and screws of the plate that supports the blades. It is not very likely if the aircraft manufacturer follows the maintenance signs.

If he loses the main rotor, he will lose direct support and start running himself. Which, with an increase in The sudden turn of the tail rotor causes the same breakIt is found in the second video, the helicopter falls to us without a rotor or tail.

The Second theory This should be done with the severe failure of the main transmission box, and if it works once, the main axis will rotate the Balas pack and the same effect on the tail transfer axis, like the previous case.

This doctrine has made a comment Helicopter pilot.

Ivan Margvez, Aeronautical engineer The work background with the simulation of the helicopter and now that he works for the airpus, it is clear that it is separated from the main rotor room, and it has entered the operation since it fell into the river.

What is vague is that the problem starts with the main rotor or the tail rotor (antibar) because the aircraft in the pictures first loses the antibar rotor, and the uncontrolled turn of the main rotor ended.

In the words of the engineer, it is very strange to see how the main rotor split and how it falls without rotating itself, and the weight of the initial loss of the Wall Roter takes weight. Ivan tells him and indicates that the pilot does not appear Structural failure For fatigue, for some Impact on an important areaMaintenance problems, bad weather or any of them with an amount or admission.

You have to wait for the final study of FAA

This type of serious complications in the helicopter are not common and it is acknowledged that it is three experts Wait to analyze the residues and the black box To get one Hypothesis It has caused a lucky accident.

There Six people have lost their livesFortunately the helicopter falls into the Hudson River and avoids additional co -damage. Relax so much The Spanish Escobar family of five people like the pilot.
