Introduction
In the aeronautics and space fields, the component life time compared to the lengthy life cycle of
finished products and the arrival of new regulations drive organisations into structuring obsolescence
management.
This need has become important in these fields as a result of:
— the effort necessary for the qualification of materials and processes (due to a high level of
performance and security requirements, to the complexity of interactions between systems, to the
large number of industrial actors, to the multinational nature of programmes, etc.);
— the regulation requirement of conformity from the produced configuration to the qualified
configuration (for example of certification by an official organization).
These characteristics reinforce three aerospace industry priorities:
— traceability;
— stability of technical choices;
— anticipation of evolutions.
New regulations such as RoHS or REACH, creating potential obsolescences (related to authorization and
substance use restriction processes), force to take this obsolescence risk into account.
They created increasingly stronger concerns for organisations willing to express a need of information
from the aerospace industry information within themselves, and within each of their programmes and
with respect to their suppliers regarding necessary and accessible data that shall be supplied, shared
and tracked. For example, information exchange principles are given in Annex A.
Obsolescence risk is meant as a potential or proven event, resulting from the non-availability of a
product.
The submentioned differentiation will be observed in obsolescence cases:
— potential: obsolescence is predicted without a known deadline;
— proven: obsolescence is indicated with a known deadline;
— endured: obsolescence was unexpected, it is assessed.
Obsolescences of chemicals and their effects on products, especially materials, processes and
mechanical part are tackled in this general recommendation, developed within the “Programme
Management” working group to which representatives of aerospace and armament industries
participated.
The obsolescences related to chemicals originate in:
— new regulations or evolution of existing laws (environment, health, safety, etc.);
— evolution for suppliers: changes of reference, evolutions of products, manufacturing processes,
formulation, rationalising of product ranges, manufacturing halts, etc.;
— supplier failure: bankruptcies, evolution of industrial organisation, industrial accidents (fire,
flooding, etc.);
— import – export obligations (ITAR, export controls, export licence, etc.);
— market laws or industrial rules (volume of production too low, ageing technology, etc.);
— etc.
1 Scope
Obsolescence is a significant risk factor for an organisation and/or a programme activity regarding the
continuity of productions, services and maintenance in operational conditions of equipments and
systems. It can appear in any phase of the product life cycle. Thus it is essential that the organisation
determines the best strategy to be implemented in order to control these risks, implying its customers
and suppliers in the definition of this strategy.
This recommendation is a document meant to be used as guidelines, for an organisation and/or a given
programme, for the implementation of a coordinated management process of obsolescence risks related
to chemical products and to their effects on products, especially on materials, processes and mechanical
parts.
Can be subject to obsolescences:
— all categories of equipments as well as their components;
— materials and processes used to produce, operate or maintain a product;
— all that can be bought, manufactured, repaired, be it done internally or externally;
— means of production, test and maintain.
This document excludes obsolescences related to electronic components and softwares (for more
information on that subject, see EN 62402).

product.
3.10
substance
chemical element and its compounds in the natural state or obtained by any manufacturing process
[SOURCE: according to GIFAS REACH Guide]

Note 1 to entry: The life cycle includes the following phases:
— initial statement of requirement;
— feasibility;
— definition;
— development;
— production;
— use;
— withdrawal.
[SOURCE: according to EN 9200]
4 Objectives of the obsolescence management process
The aim of this process is to ensure that the product, subject of the programme, can be manufactured
and supported throughout its life cycle (maintenance, spares, reparations, etc.). It enables to anticipates
obsolescences and minimise their impact and their cost on the products of the organisation (actual and
in the near future).
The process consists in scheduled and coordinated actions intended to ensure the availability of a
product during its operating life, through technically and economically practicable means of
replacement.
The process shall include the strategic vision of the operators of the supply chain (this vision can differ
