COP reviews
Conformance of Production arrangements assessed against what the regulator expects to see.

Will what you build still match what was approved?
An approval is a statement about a specification. Conformance of Production is the evidence that what leaves your line still matches it. We run COP reviews, prepare NRCS surveillance audits, and keep conformity guidance in place so an approval holds after it is issued.
Conformance of Production arrangements assessed against what the regulator expects to see.
Inspection readiness, so an audit confirms what you already know rather than discovering it.
Production conformity alignment between units, not just on the approved sample.
A written assessment of where your evidence and your practice diverge.
NRCS, DoT, testing facilities and stakeholders coordinated on your behalf.
COP, audits and ongoing conformity so compliance is sustained rather than one-off.

It can, particularly on safety-critical components. Change notification and impact assessment is part of keeping an approval valid.
