Topendtorque, I'm not sure that it's fair to say that the Chief of the Defence Force should have to be responsible for the selection, training and recurrency training of a squadron of pilots. He is, after all, responsible for the Army, Navy and Air Force (about 85000 people) and has a bunch of other people who actually have the hands-on responsibility.
He probably has responsibility though to take action once he discovers a problem which it sounds as though he is doing, having apparently commissioned an inquiry into his helicopter operations following his receipt of the BOI report.
