“Visit the scene of the accident; have access to the relevant information which is approved for public release by the state conducting the investigation, and information on the progress of the investigation; and receive a copy of the final report,” the statement read.

“This participation ensures access to relevant information and facilitates cooperation with the investigating authorities, towards ensuring the investigation reaches a conclusive outcome.
“The ongoing discussion between the NSIB and NTSB has highlighted the diligent investigation efforts of the NTSB. NTSB investigators were present at the crash scene in Halloran Springs, California, on Saturday to collect evidence and conduct initial on-scene documentation.
“The documentation process included aerial mapping of the wreckage with a drone, and site measurements.
“Correspondence between the NSIB and NTSB further revealed that the NTSB investigation into the crash is being led by Aaron Sauer as the investigator in charge, supported by Mark Ward as the deputy investigator in charge.

The bureau noted, “All significant components of the helicopter, including the main transmission, engine, and various avionic elements, were identified and accounted for at the accident site.
“In tandem, the operations investigation group has commenced gathering crucial company information, including pilot records, flight dispatch records, and aircraft maintenance records.
“Moving forward, coordination is underway by the NTSB to transfer the wreckage to a secure location on Tuesday for in-depth examination and analysis scheduled.
“Parties to the investigation include Orbic Air, LLC, and the FAA. As the investigation continues, other parties could be named.
“Additionally, the Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA), the French aviation accident investigation agency, will also serve as an accredited representative, due to France being the state of manufacturer for the Airbus helicopter and Turbomeca Engine.
“Both Airbus Helicopters and Turbomeca Engines will serve as technical advisors to the investigation.”
