GM 21.A.126(a)(1) Production inspection system – Conformity of supplied parts, appliances and material    

CAA ORS9 Decision No. 1

1. The person producing under Subpart F is responsible for determining and applying acceptance standards for physical condition, configuration status and conformity, as appropriate, of raw materials, subcontracted works, and supplied products, parts, appliances or material, whether to be used in production or delivered to customers as spare parts. This responsibility also includes BFE (Buyer Furnished Equipment) items.

2. Control may be based upon use of the following techniques, as appropriate:

2.1 first article inspection, including destruction if necessary, to verify that the article conforms to the applicable data for new production line or new supplier,

2.2 incoming inspections and tests of supplied parts or appliances that can be satisfactorily inspected on receipt,

2.3 identification of incoming documentation and data relevant to the showing of conformity to be included in the certification documents,

2.4 any additional work, tests or inspection which may be needed for parts or appliances which are to be delivered as spare parts and which are not subject to the checks normally provided by subsequent production or inspection stages.

3. The person producing under Part 21 Subpart F may rely upon the CAA Form 1 issued in accordance with Part 21 if provided as evidence of conformity with applicable design data

For suppliers not holding a POA the inspection system of the person producing under Part 21 Subpart F should establish a system for control of incoming materials and bought or subcontracted items which provides for inspections and tests of such items by the person producing under Part 21 Subpart F at the supplier’s facility, if the item cannot or will not be completely inspected upon receipt.
