Technical obsolescence resolution encompasses all activities required to deliver a supply solution. Check out our support


the context

There are several resolution pathways depending on the criticality of the obsolete component :

Building a strategic stock during a manufacturing stoppage alert

The search for a substitute:

  • Equivalent substitute whatever the use case:Real equivalence (preferred solution)
  • Replacement substitute with acceptable deviations for a given use case:Approximate equivalence
  • Replacement substitute with unacceptable deviations for a given use case: Change of definition



our team

The teams are made up of general engineers because of the vast scope of spare parts families concerned.The assignments implemented are:

Prioritising the processing of the obsolescence alerts

Proposing solutions, requesting stock transfers

Searching for specific features for each case with upstream specifications or questions from manufacturers/industrialists

Writing/validating compatibility analysis sheets for each use case via

  • Functional and reliability analysis (suitability of the technical characteristics)
  • Implementation analysis (conditions of use)
  • Data entry to the information system (traceability)
  • Completing the alert forms for development requests
  • Sending validated references for CIMD coding

our support

The technical obsolescence resolution activity is integrated within the assignments deployed to numerous clients in mixed site/Agency outsourcing in TS or on-platform:

  • Since June 2014 at ArianeGroup on the mechanical floor resources and secure infrastructures
  • Since February 2017 on all the Thales DMS and military AVS carriers
  • Since July 2017 on aeronautical consumables Thales LORCA contract

Technical obsolescence resolution is possible in the following business families:

  • All mechanical parts (hardware, lifting or rolling equipment parts, aeronautical parts)
  • All electrical/electronic/electromechanical parts
  • Fluids (greases, oils, fuels)
  • Others (paints, infra equipment)

As a result of Apside’s support, the management of obsolescence lines has significantly increased as well as the resolution of a certain number of them by offering the customer relevant and usable solutions. As a result, we were able to guarantee the supply of the aeronautical consumables needed for the industrial maintenance activity and/or operational workshops of our customers. The relationship with the customer is very close because the issues concerning the availability of parts/equipment on operational sites are crucial.
