Unfortunately when fatalities & or serious injuries occurr you move without the RAF Just culture & into the civil law,which is neither just or fair.
Although there is a reactive element,the main thrust of trying to foster a just culture, is to move from reactive,through proactive & onwards to predictive.
People need to report, to highlight those pre-cursor events which lead to platform loss & fatalities. Having worked with the FAA they are a long way behind the curve,there is a huge element of complacency regarding Just Culture,reporting & investigation. See the Semmelwiess reflex. There is a huge disconnect between command & the coal face,they don't have a scooby about the unwarranted risks their people are taking.
