The MAIB’s sole objective in investigating an accident is the prevention of future accidents by establishing its causes and circumstances: it is not the purpose to apportion liability, nor except so far as is necessary to achieve the objective, to apportion blame. The MAIB is not an enforcement or prosecuting body.
