(1) If an approved maintenance organisation knows that a part that is not fitted to an aircraft is unserviceable, the organisation must ensure that the steps mentioned in subregulation (3) are taken within 2 days after the organisation first knew that the part was unserviceable.
(2) If an independent maintainer knows that a part that is not fitted to an aircraft is unserviceable, the independent maintainer must take the steps mentioned in subregulation (3) within 2 days after the independent maintainer first knew that the part was unserviceable.
(3) The steps are:
(a) applying a label, or attaching a tag, to the part recording the following:
(i) sufficient information to identify the part, including the part's name, part number and serial number (if any);
(ii) that the part is unserviceable;
(iii) the origin of the part, including information about the aircraft or aeronautical product from which the part has been removed, if relevant and if known to the independent maintainer or organisation;
(iv) the reason that the part is unserviceable; and
(b) if the independent maintainer or organisation keeps the part--storing the part separately from serviceable aeronautical products and in a secure location.
