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.
The Accident Investigation Bureau (AIB) investigates aircraft accidents and incidents in Nigeria. It is headquartered on the grounds of Murtala Muhammed International Airport in Ikeja, Lagos State.
The agency reports to the President of Nigeria through the Federal Minister of Aviation. The agency’s Commissioner, who is also the Chief Executive Officer is Mr. Akinola Olateru. (The agency’s former Commissioner was Dr. Felix Abali.)
Previously the Ministry of Aviation Civil Aviation Department investigated aircraft accidents. In 1989, the Federal Civil Aviation Authority (FCAA) opened, and the Civil Aviation Department became the FCAA Department of Safety Services.
During the same year the Accident Investigation Bureau (AIB), subordinate to the Ministry of Aviation, was established, and the FCAA no longer had accident investigation responsibilities. The name of the bureau was later changed to the Accident Investigation and Prevention Bureau. As part of the Civil Aviation Act of 2006, the AIB became an autonomous agency.
