A person may ask CASA in writing to review the operation of an Australian airworthiness directive on the ground that all aircraft or aeronautical products covered by the Australian airworthiness directive, or all aircraft or aeronautical products of a kind mentioned in the request (being aircraft or aeronautical products covered by the Australian airworthiness directive), need no longer be covered by the Australian airworthiness directive because:
(a) the instructions issued by the manufacturer or manufacturers of those aircraft or aeronautical products for the carrying out of maintenance on those aircraft or aeronautical products have been amended; and
(b) if maintenance is carried out on those aircraft or
aeronautical products in accordance with those instructions as amended, the
unsafe condition that the Australian airworthiness directive seeks to correct
will no longer exist, or is not likely to exist, or cannot develop, in those
aircraft or aeronautical products.
