The NTSB also said that โNo onboard video recorders or camera recorders have been recovered.โ
While divers continue to use โside-scanning sonarโ to search the waters of the Hudson River for wreckage from the tourist helicopter crash last week that killed six people, the National Transportation Safety Board (NTSB) said on April 12 that the aircraft was not equipped with flight recorders.
โThe helicopter was not equipped with any flight recorders. No onboard video recorders or camera recorders have been recovered, and none of the helicopter avionics onboard recorded information that could be used for the investigation,โ the NTSB wrote in a Saturday investigation update.
The agency said the helicopter, a Bell 206 L-4, had its last major inspection on March 1. On April 10, the day the crash occurred, the helicopter had completed seven tour flights and the accident happened during its eighth flight, according to the NTSB.
New York Police Department divers are still searching for the helicopterโs main rotor, main gear box, tail rotor, and a large portion of the tail boom, using side-scanning sonar to identify potential wreckage locations. The recovery operations are continuing on Sunday, the NTSB said.
So far, divers have recovered the main fuselage, including the cockpit and cabin, the forward portion of the tail boom, the horizontal stabilizer finlets, and the vertical fin. The NTSB said some of the recovered parts will be sent to its laboratories in Washington for further inspection.
The agency said its investigators met with representatives from the helicopterโs operator, New York Helicopter Charter Inc., to review its operational records, policies and procedures, safety management systems, and the pilotโs experience. The NTSB will also inspect two similar helicopters.
The Federal Aviation Administration, Bell Helicopter, and Rolls Royce are contributing to the investigation. The NTSB said it will release more information as it becomes available.
Six people died after the helicopter careened into the Hudson River just off Manhattan on April 10. The incident occurred at 3:17 p.m. on Thursday in the vicinity of the West Side Highway and Spring Street on Manhattanโs west side, according to the New York Police Department.
