The flaw IMHO to all the plans, clever or otherwise, to oblige the MOD to make airworthy their unairworthy aircraft, whether in service now or in the future, is that it has to balance such expenditure with all the other calls on its budget, shrinking or otherwise. The government is thus off the hook and can move the goalposts adinfinitum, a la UORs. It needs an external authority to oblige the MOD to commit to such expenditure and oblige it to make its air fleets fit for purpose. The answer to MRA4 airworthiness, as it is with every other type, is an MAA. This is a vital imperative. Our armed forces need kit that is fit for purpose to prevail in the wars that they are sent to by this government, that especially includes the aircraft that are an integral part of that effort. The only way to assure that is to establish an MAA without delay.
