The Accident Investigation Bureau has released the preliminary report of the helicopter accident involving the Vice President, Prof. Yemi Osinbajo.
The Commissioner, AIB, Mr. Akin Olateru, on Thursday said the investigation was still ongoing but that among other causal factors, the crew lost visual contact with the ground at landing due to a “brownout.”
According to him, brownout is caused by landing in a dry, sandy environment.
“Caverton Helicopters Limited did not conduct 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 injury in the crash.
