My point? An effective BOI means doing something about the problem, not just neatly and accurately identifying it.
You have now moved the argument into new territory. Whether the MoD agrees the recommendations of the BoI and implements them is a totally different matter. What is important here is that the MoD
places itself on record as to why it does or does not agree and why it has or has not implemented a change to equipment/regulation. For example, in the case of the Lynx fuel system it may have been: cost vs other programmes in the budget;operational impact on performance;risk considered worth it (not forgetting it is an armed service not a civil airline ie acceptable risk factors may be higher for MoD). It also needs to explain to its people why it has not accepted the recommendations. Once again the RN has such a system in place called the Post Accident Follow Up System where each recommendation is tracked until the issue is closed by the RNFSAIC.
