Why Did a Helicopter Crash in NYC’s Hudson River? What We Know so Far.

There are numerous questions swirling after a vacationer helicopter crashed into the Hudson River in New York Metropolis on Thursday, killing Siemens Mobility govt Agustín Escobar, his spouse, and three kids.

The pilot, who the Nationwide Transportation Security Board stated on Friday had about 788 hours of whole flight expertise, additionally died.

The 21-year-old Bell 206 helicopter, registered N216MH and operated by New York Helicopter, plummeted into the river off the New Jersey shoreline at round 3:15 p.m.

It crashed the other way up after what seems to have been a midair breakup. The plane was owned by Louisiana-based Meridian Helicopters, LLC, whose web site says it sells, refurbishes, and leases helicopters. Meridian did not return an e mail or telephone message from BI.

Former army helicopter pilot Brian Alexander informed Enterprise Insider that the accident seems to have been a results of a “catastrophic mechanical failure” involving each the principle and tail rotors.

He stated no trigger is confirmed and other people ought to watch for the NTSB’s investigation earlier than leaping to conclusions. Alexander is also a associate at aviation accident legislation agency Kreindler & Kreindler.

Whereas Thursday’s helicopter crash may spark renewed fears amid a current spat of airline accidents, the trigger is unlikely to be associated.

Why did the helicopter crash?

Movies posted on social media present the helicopter’s rotary programs apparently indifferent mid-flight, falling into the water after the plane’s primary physique had already crashed.

“It is onerous to say which got here first,” Alexander stated. “There seems to be spinning, which might recommend a tail rotor concern, however you may’t rule out a primary rotor detaching first and hitting the tail rotor.”

The spinning he is referring to is the helicopter fuselage because it fell into the Hudson, which he stated means the tail rotor doubtless failed in some unspecified time in the future.

He defined that with out a tail rotor, the helicopter would “spin like a prime” as a result of torque created by the principle rotor because it produces raise and thrust. Both or each programs failing may result in an accident.

“If you happen to lose your primary rotor, that means it is indifferent, you don’t have any raise, you are carried out,” Alexander stated. “There’s nothing you are able to do at that time; you are only a falling object.”

He stated a helicopter that loses only a tail rotor is a extreme scenario, however it might nonetheless be flown — although with nice issue.

Alexander stated that shedding energy is usually a extra surmountable concern. In a state of affairs the place the helicopter’s engine failed, and the blades have been nonetheless connected, the plane may auto-rotate to descend to land.

NTSB Chairman Jennifer Homendy stated on Friday that a part of the wreckage had been pulled from the river, however dive groups are nonetheless retrieving elements, together with the principle and tail rotors.

She stated the company “doesn’t speculate” on possible trigger and nonetheless wanted to collect the sunken elements, conduct witness interviews, and collect data like upkeep logs.

Why did the rotors apparently detach?

Alexander stated that there are a number of causes the helicopter rotors may detach, like mechanic error or a transmission concern.

He additionally stated the mast — which connects the principle rotor hub to the transmission — may have disconnected totally.

“Somebody on the upkeep aspect perhaps did not tighten a bolt up, or a component simply failed,” he stated, emphasizing that any trigger remains to be unknown. “I am positive that is what [investigators] will probably be taking a look at.”

This would not be the primary time a helicopter owned by Meridian and operated by New York Helicopter skilled a system malfunction.

In 2015, the tail rotor driveshaft on one other one of many firm’s Bell 206 helicopters indifferent, which induced a lack of management and onerous touchdown in New Jersey, in accordance with the NTSB.

The pilot, who was the only occupant, was unhurt.

The driveshaft transmits energy from the transmission to the tail rotor. Nonetheless, the NTSB decided that the one put in was “unairworthy.”

Meridian informed the NTSB that the driveshaft was bought at public sale by the helicopter’s earlier proprietor after the identical helicopter skilled a separate onerous touchdown in 2010.

Inspectors discovered the driveshaft had been repainted, corrosion had been eliminated, and the serial quantity didn’t match recognized data — that means they may not decide if it was the identical driveshaft that was connected to the helicopter through the 2010 onerous touchdown.

The NTSB decided that the possible explanation for the 2015 crash was the “deliberate concealment and reuse” of a defective driveshaft “by “unknown personnel.”

New York Helicopter did not reply calls from BI; its president declined to remark to The Wall Road Journal.

How usually do helicopters crash?

Whereas helicopters are usually protected as long as security procedures are adopted, they’ve a relatively greater crash price than business airplanes due to their riskier advanced programs and working surroundings.

Helicopters have extra shifting elements, require extra changes, depend on auto-rotation to emergency land moderately than glide, function at decrease altitudes, and generally fly in much less managed airspace.

Transportation Secretary Sean Duffy stated on X that Thursday’s helicopter was flying within the Particular Flight Guidelines Space on the time of the crash, the place there isn’t any air visitors management assist.

Information from the US Helicopter Security Workforce reveals there have been about 90 helicopter accidents in 2024, 13 of which led to 30 collective fatalities.

An Related Press report stated no less than 32 folks have been killed in helicopter crashes in New York Metropolis between 1977 and 2019.

5 folks died in 2018 when a helicopter crashed and flipped the other way up within the East River. A 12 months later, a helicopter crash-landed on the roof of a Manhattan skyscraper, killing the pilot.

The accidents have sparked restrictions on issues like flight paths and touchdown spots to enhance security.

Alexander stated that whereas helicopter crashes are extra frequent, full primary rotor detachment is uncommon. “Every little thing about that is uncommon,” he stated. “You simply do not see one thing like what all of us noticed.”
