This was made known by the AIB Commissioner, Mr Akin Olateru who said there is still an ongoing investigation on the accident.
According to him, he said the crew lost visual contact with the ground at landing due to a “brownout.
He stressed that the brownout is caused by landing in a dry, sandy environment.
“Caverton Helicopters Limited did not conduct a site survey of the landing field prior to the flight and did not carry out safety and risk assessment,” he said.
A helicopter conveying the Vice President to a campaign rally in Kogi State had crash-landed in Kabba on February 2.
Nobody died or sustained an injury in the crash.
