Either I'm misunderstanding or you're misreading...when you link as per #306, the TAM page of course shows today's date in the header but their MEL extract (which they put into the public arena as presumably the document current at time of accident) shows 20/7, the date of the press release. The MEL itself is undated, hence my and others' queries about when the procedure was changed from the intuitive "don't use it if it's broken" to "use both anyway".
