She said that as of Friday, three individuals remained unaccounted for, and long-term search efforts continue in coordination with local and international partners.
She added that further updates would be provided as the investigation progressed and significant developments emerged.
The NSIB Director-General, Capt. Alex Badeh commended the recovery teams and stressed the importance of the investigation.
“The recovery of the Flight Data Recorder and Cockpit Voice Recorder marks a monumental step in understanding what led to this tragic accident.
“The black box holds vital information that will provide invaluable insight into the sequence of events leading up to the accident, which will help us to determine the cause and inform any necessary safety recommendations.
“While our thoughts are with the families of those still unaccounted for, concerted efforts are being made to find the missing individuals and provide answers to the families affected by this accident, ” he said.
NAN also reports that the NSIB has recovered the bodies of five of the eight individuals said to be aboard the ill-fated helicopter.
