The purpose of a Regularity Authority is not to bring aviation to a halt, on the contrary it is to keep it airworthy and therefore flying. If the MAA is not doing that you have my sympathy and it confirms my suspicions that this is not a Regulator but a bureaucracy, busy at being busy. It cannot do its job because it does not know how nor even if it did, despite how you feel, the clout. If it had the clout, practices as have been described here and elsewhere would not occur as they would be jumped on from a great height. The MAA cannot climb to any great height so it wastes its time snapping at peoples heels. Meanwhile the chronic condition of UK Military Airworthiness continues, waiting to manifest itself in another sad thread on this very forum. We have to beat it to it!
