Tuc, it seems that you only have to lift any MOD airworthiness rock to find something very unpleasant slithering desperately to avoid being seen. From a position of proposing that there may be specific problems with specific aircraft types, the MOD's record shows that the whole system of UK Military Airworthiness under the MOD is broken. No fleet is unaffected, as the rot is endemic throughout. Blame and consequences are secondary to urgent remedial action. Notice I do not say "swift", for the system may be broken simply by a two star ordering his subordinates to flagrantly ignore their mandated duty to enforce the airworthiness regulations; that's the swift part, as breaking the system merely requires "good men" to do nothing. Restoring airworthiness to the military airfleets will take much longer, decades perhaps, and some fleets will never attain the status of airworthiness before they are scrapped. All the more reason to initiate reform ASAP, and that reform begins only when the MOD is no longer responsible for UK Military Airworthiness Regulation enforcement.
