(CNN)Months before a helicopter crashed in New York’s East River, killing five people, pilots at Liberty Helicopters warned management of safety issues, an attorney representing several pilots said.
Five people died when the Liberty Helicopters chopper crashed on March 11. The pilot, who managed to free himself, was the sole survivor.
The passengers had chartered the trip for a private photo shoot through FlyNYON, a tourist helicopter company.
The helicopter, with the doors removed so passengers could take unobscured photographs, had engine problems and crashed in the East River.
The pilots who made the warnings were not identified, but Katz said some still work at Liberty Helicopters and others had been employed by the company. Katz said the pilots sent emails to management at Liberty Helicopters and FlyNYON, discussing safety concerns.
Patrick Day, chief executive officer of NYONair, said the company rejects the “allegation that anyone at FlyNYON did not heed issues” cited by Liberty pilots. His company also rejects claims it “failed to respond to safety concerns,” he said. FlyNYON is a company of NYONair.
“FlyNYON takes great pride in the safety of our operation. We trusted the pilots, the aircraft and the operation sufficiently to put our own staff and families on doors-off flights regularly,” Day said in a statement given to CNN on Sunday.
It was Liberty Helicopters’ third crash in the past 11 years. CNN has reached out to Liberty Helicopters for comment.
Crash prompts industry review
The commercial air tour industry is facing increasing scrutiny after the crash.
After what experts described as years of scant oversight, the Federal Aviation Administration is conducting a top-to-bottom review of its rules governing the industry.
The FAA issued an order suspending “doors off” flights involving “restraints that cannot be released quickly in an emergency.”
The order affected “several dozen” national helicopter tour companies offering doors-off flights, the FAA said.
The NTSB had said the harness used by the passengers on the chopper was not evaluated by the FAA. The system was not installed by Liberty Helicopters but was a collection of “off-the-shelf components” provided to the passengers by FlyNYON, the agency said.
The level of instruction offered to passengers has also come into question since there’s no requirement to specifically instruct passengers on escaping harnesses during an emergency.
“This accident has the potential to be a watershed event for the industry,” Peter Goelz, a former managing director of the National Transportation Safety Board had said.
Engine showed no sign of abnormalities
Before the crash, the pilot “observed engine pressure and fuel pressure warning lights and believed he had experienced an engine failure,” according to a preliminary report by the National Transportation Safety Board.
As the pilot made his way to the East River to execute an emergency landing, “he reached down for the emergency fuel shutoff lever, he realized that it was in the off position. He noted that a portion of the front seat passenger’s tether was underneath the lever.”
The pilot attempted to restart the engine as the helicopter fell toward the river, but the engine “wasn’t spooling up fast enough,” leading him to turn off the emergency fuel lever again, the report says.
The NTSB said it had interviewed Liberty Helicopters’ personnel, including the pilot, adding that the helicopter’s engine showed no sign of abnormalities.
When the helicopter crashed, the five passengers drowned because they were unable to break free from harnesses meant to prevent them from falling out.
The pilot told NTSB investigators he provided a safety briefing to the passengers before takeoff. The briefing included a description of how to use a cutting tool to sever their restraints, the pilot said.
Day said the FAA in October finished a “site inspection” of a flight operated by Liberty Helicopter with FlyNYON passengers.
“Inspectors observed the harness and tethering process and continued to permit their use on Liberty and FlyNYON operated flights without issue,” Day said.
He said the company hopes the NTSB will come up with “all of the causes of this tragic accident” and that FlyNYON will be working closely with authorities.
“It is our pilots that interface with our customers and keep them safe. We value our pilots, and all our employees, above all else, always have, and not only appreciate their input but actively encourage them to contribute,” he said.
