One Part, Many Compliance Stories

A question for the equipment suppliers and ETSO manufacturers here:

You build one "part". But its compliance evidence has to feed upward into several different TC and STC holders, and each of them wants it structured their way, referenced their way, delivered on their timeline.

So one part quietly becomes many compliance stories, maintained in parallel, drifting out of sync the moment anything changes.

I mostly talk to DOAs on the integrator side. I'd like to understand this from the supplier's chair.

Is that your reality, or am I describing the wrong problem?
