ED Decision 2023/013/R
QUALITY SYSTEM — CONFORMITY OF SUPPLIED ITEMS
The declared production organisation is responsible for determining and applying acceptance standards for the physical condition, configuration status and conformity of supplied products, parts, materials or equipment, whether to be used in production or delivered to customers as spare parts. This responsibility also includes items of buyer-furnished equipment (BFE).
To discharge this responsibility, the quality system needs an organisational structure and procedures to adequately verify the supplied items.
The below list provides examples of verification techniques to be used as appropriate to ensure conformity of the product or part:
— qualification and auditing (desktop and on-site audits) of the supplier’s quality system;
— evaluation of the supplier’s capability in performing all the manufacturing activities, inspections and tests necessary to establish the conformity of parts, materials or equipment to the applicable design data;
— first-article inspections of supplied parts, including destruction, if necessary, to verify that the article conforms to the applicable data for a new production line or a new supplier;
— incoming inspections and tests of supplied parts, materials or equipment that can be satisfactorily inspected on receipt;
— identification of incoming documentation and data relevant to the showing of conformity to be included in the certification documents; and
— any additional work, tests or inspection which may be needed for parts that are to be delivered as spare parts and which are not subjected to the checks normally provided by subsequent production or inspection stages.
The declared production organisation could for example rely on the results of inspections/tests performed by the supplier, if the supplier can establish that:
— the personnel responsible for these tasks satisfy the competency standards of the declared production organisation quality system;
— quality measurements are clearly identified; and
— the records or reports showing evidence of conformity are available for review.
For the purpose of showing conformity, a declared production organisation could for example rely upon an EASA Form 1 issued by the supplier.
If the items are not delivered with an EASA Form 1, the supplier is considered a subcontractor under the direct control of the quality system of the declared production organisation.
Since the declared production organisation is responsible for the verification of the supplied items, it retains direct responsibility for inspections/tests carried out either at its own facilities or at the supplier’s facilities.
Production organisations must verify supplied items' conformity, using audits, first-article inspections, and supplier reliance, with EASA Form 1 or subcontractor control.
