Anotation

This document defines the common NOC requirements for aviation, space, and defence organizations. The requirements that a design organization uses when submitting a NOC to the customer for either change authorization or notification are included herein. A NOC informs the customer of physical or functional (e.g. design, material, software, maintenance) changes or any associated process changes to an established baseline configuration.
Retention of the NOC establishes a means of configuration control and captures the evolution of the part. This requirement is of utmost importance in commercial/civil aviation products where changes to type certificated products are mandated by regulations; however, these same concepts are also required in defence and space applications per contractual requirements.
Where there are changes to items which the organization does not have design input or is not permitted to make any changes to the design [e.g. build to print, Technical Standard Order (TSO) articles] then change requests are formally submitted to the customer and approved via the customer´s change request process.
This document is not applicable to commercial parts [off-the-shelf items not specifically designed for aviation, space, or defence products; aka Commercial off-the-Shelf (COTS)] for which changes in product definition is not affected or known. COTS items that are modified or altered are subject to the requirements herein. When this document is applied to an organization that distributes a product, then this document is also a requirement to the organization from which the product is procured by the distribution organization
