In order to perform
Controlled processes on material or articles for United Space Alliance
(USA), a supplier must have a separate operator-level Controlled
Processing Procedure (CPP), which has been approved by USA for the
revision being used. If an existing supplier document satisfies CPP
requirements, the supplier may identify such document as an CPP and
submit this document to USA for approval. Supplier shall maintain a
document release and change control system for CPPs.
Supplier shall also maintain a historical file for CPPs
including applicable substantiating process qualification test data and
other records traceable to the CPPs.
Any change to a CPP shall be approved by USA prior to
implementation. To be acceptable, the CPP must include the following
information, as applicable. Format and sequence of presentation are the
supplier’s option. |
