A new report released by the Accident Investigation Bureau has blamed the 2012 helicopter crash involving a Deputy Inspector-General of Police in charge of operations, Mr. John Haruna, and three others in the Kabong Area of Jos, Plateau State, on pilot error.

The report released on Wednesday stated that the medical certificate of the pilot of the bell 427 helicopter, with registration number 5-NPAL, had expired as of the time of the accident, while the co-pilot was not type-rated on the helicopter.

Although the AIB commissioner, Mr. Akin Olateru, said the cause of the accident could not be conclusively decided, the investigation discovered a series of discrepancies and non-compliance with the Nigerian Civil Aviation Regulations.
