In some cases, parts may be classified as NFC. During the classification of all parts in accordance with section 4.3 [FCR 5] in this NASA Technical Standard, the hardware developer identifies the applicable approaches or activities of this section for each of the parts that are to be classified as NFC and documents them in their hardware-specific FCP. The RF CB reviews and approves the FCP to ensure that it includes all specified elements of the selected approaches.
The methods in this section are based on NASA’s experience base, established approaches, industry standards, or aerospace standards. Any deviations or omissions of elements in the activities or approaches prescribed in this section constitute an alternative approach that is to satisfy the requirements in section 10 [FCR 26] in this NASA Technical Standard.
NFC parts are those shown in the hardware-specific FCP to meet a category in this section, which typically involves documentation of an assessment involving some combination of analysis, test, inspection, failure mode evaluation, or adherence to specified criteria listed in each subcategory. The documentation is to be cited in the FCSR where the part is listed as NFC in accordance with section 9 requirements in this NASA Technical Standard.
Parts that are identified and shown to meet NFC classification criteria in documentation cited in the FCSR in accordance with section 9 requirements in this NASA Technical Standard comply with fracture control requirements without further activity beyond conventional aerospace verification and quality assurance procedures, unless otherwise indicated in this document.
