I just had a browse through the CASA regs and my interpretation is that a serviceable genuine part does not need an original manufacturer's release note. We just had an example of this..We gave our magneto to a Lame to be inspected. No paperwork provided to him, just the magneto. It came back with a release note. My reading of the reg below is that you just have to be able to establish that the part is the real thing. Some of the "evidence" required by the following text could simply be an examination by a qualified person. In the CASA world if you lose a release note you don't have to throw away the part.........you just get an inspection done and new release note issued 42.445 Fitting standard parts
(1) An individual who is carrying out maintenance on an aircraft or aeronautical product must not fit a standard part to the aircraft or aeronautical product unless the fitting of the part is permitted under: (a) regulation 42.450; or (b) subregulation (2). Subregulation (2) For paragraph (1) (b), the standard part may be fitted if: (a) the standard part is serviceable; and (b) the standard part is accompanied by: (i) information that identifies the specification with which the part complies; and (ii) information that allows the part to be traced to its manufacturer; and (c) the standard part is accompanied by evidence that the standard part complies with the specification; and (d) the standard part is eligible to be fitted to the aircraft or the aeronautical product; and (e) if the manufacturer of the standard part has specified a storage life for the part — the storage life for the part has not expired.
