The Accident Investigation Board (AIB) constituted by the Nigerian Air Force at the instance of the Nigerian Navy to ascertain the cause of the fatal crash involving the Nigerian Navy Agusta helicopter which occurred on 15 December 2012 has submitted an interim report to the Naval Headquarters.
The Investigation which was conducted by aviation experts in collaboration with the manufacturers – Agusta Westland has stated that the cause of the crash could either be human error or material failure or a combination of both. However, to determine the actual cause of the crash there, would be the need to tear down the engine of the helicopter in order to carry out detailed forensic analysis. This aspect of the investigation will be carried out by Turbomeca, the manufacturers of the engine.
It is important to emphasize that an independent police report has equally ruled out sabotage as a possible cause of the crash. Further information on the investigation would be made public when available.
