Annex X: LLP Back-to-Birth Guidelines
4.1 LLP Birth (Manufacture)
The OEM produces the first document for the part at production. Although there are no specific regulatory
requirements to keep proof of manufacture on file, it is commonly accepted (and reasonable to expect) that a
manufacture document is provided, showing birth for each LLP. Such a document should be one of the
following items:
●
OEM document confirming the LLP was installed in an engine/APU/gear during production. Different
OEMs provide different types of documents, and therefore the following list is not exhaustive. Possible
OEM documents are:
o
o
o
o
o
EDS (Engine Data Submittal)
VSL (Vital Statistics Log)
IIL (Industry Item Listing)
OEM logbook with LLP log cards
ARL (Aircraft Readiness Log)
o AIR (Airbus Inspection Report) - Folio 12
o
o
IOC (Installed Original Components)
ASL (Aircraft Serialization Listing)
Such a document should include the following information:
o
o
o
o
o
o
S/N of new engine/APU/gear on which LLP was installed during production
Model Number and thrust rating/TO weight as applicable for new engine/APU/gear on which LLP
was installed during production
P/N of LLP
S/N of LLP
Description of LLP
If applicable, TSN/CSN/time of LLP accumulated as part of engine/APU/gear testing performed by
the OEM
●
Certificate of Manufacture or OEM Packing List
If an LLP was installed new into an engine/APU/gear during a shop visit, then there should be a
certificate of manufacture for the new LLP. This is usually an EASA Form 1, an FAA 8130-3 or a Transport
Canada Form 1, as applicable.
In some cases when OEMs sell new LLPs inside the US, only a Packing List 22 is provided without FAA
8130-3. Such a Packing List is acceptable if it comes from the relevant OEM, and indicates the LLP P/N,
LLP S/N, and a confirmation that the listed parts are new.
