Amendment 1/2007 to CAP 393 has just been issued (last week) and the ANO now, among other things, defines all references to JAR-FCL 1 as being to Amendment 5 of that document. It is Amendment 5 that introduced the requirement for all renewals of IR(A)s to be done on the aeroplane as well as every other revalidation. Therefore the CAA man's comment that "it will change shortly" was correct - it has!
