Suspected Unapproved Parts (SUP) includes products, components, or materials, from unknown, or suspect origin, or unserviceable critical components. The part itself or its associated paperwork can call it into question.
When in doubt about the origin of a part, maintenance organisations, aircraft owners, operators, independent certifying staff, manufacturers, and parts suppliers should check the information in the SUP list before accepting the part into stock or fitting it to an aircraft.
If a part in the SUP list is held in stock, it should be quarantined until a determination can be made regarding its eligibility for installation.
The UK CAA cannot always resolve SUP cases, mainly due to the lack of required information. For example, when:
- A SUP with an allegedly forged Authorised Release Certificate comes from a non-UK maintenance organisation, supplier or distributor and it is difficult to obtain feedback from the National aviation safety authority.
- The origin of the SUP is impossible to determine.
- A potential buyer has been sent an Authorised Release Certificate for pre-assessment and they believe that the documentation has questionable provenance indicating that an SUP case might exist.
- A part was unlawfully removed from a maintenance facility and is expected to appear on the market with forged documentation or untraceable history.
Reporting
A SUP should be reported by completing a Suspected Unapproved Part Report and emailing it to SUP@caa.co.uk
The UK CAA’s mandatory reporting system has been established under Article 4(3) of Regulation 376/2014. Implementing Regulation 2015/1018 defines one of the occurrences subject to reporting as ‘the use of products, components, or materials, from unknown, suspect origin, or unserviceable critical components’ (SUP).
