RA 5885 – Identification of Products, Parts and Appliances
(MRP 21 Subpart Q)
1
Rationale
To comply with configuration control requirements, each product , part or appliance to
be fitted on an Air System must be individually identified. There are important safety,
operational and economic benefits if the possibility of recurrent failure of a product,
part or appliance can be confined to identifiable material batches, components,
equipment or aircraft. To achieve this, traceability and interchangeability are required
for selected products, parts and appliances.

Identification of Products
5885(1)
5885(1)
The identification of products shall include the specific
information of Manufacturer's name, Product designation,
and the Manufacturer's Serial Number.
Acceptable Identification of Products
Means of
1.
Any organization that manufactures an aircraft or engine should identify that
Compliance aircraft or engine by means of a fireproof plate that has the information specified in
RA 5885(1) marked on it by etching, stamping, engraving, or other approved method
5885(1)
of fireproof marking. The identification plate should be secured in such a manner that
it is accessible, legible and not likely to be defaced or removed during normal service
(including maintenance), or lost or destroyed in an accident.
2.
Any organization that manufactures a propeller, propeller blade, or propeller
hub should identify it by means of a plate, stamping, engraving, etching or other
approved method of fireproof identification that is placed on it on a non-critical surface,
contains the specified information, and is not likely to be defaced or removed during
normal service or lost or destroyed in an accident.

the information that could not be marked on the part.
8.
Any private markings used by the manufacturer to facilitate the assembly of
parts should not be located in a position where they will confuse other identification
marks.

Regulatory Article 5885
The Design Organization shall prepare, for inclusion in the
Design Records, a list of all Identifiable Parts. The list shall
be agreed with the TAA and kept under review in the light of
service experience and changes in design.
Acceptable Traceability of Identifiable Parts
Means of
12. The list of Identifiable Parts should also include Critical Parts and those parts
Compliance likely, in the case of a fault, to affect airworthiness or operational effectiveness. Thus
all Grade A parts (refer to Def Stan 00-970 Part 1, Section 4.1 and Part 7, Leaflet 400)
5885(5)
should be included.
