How the MOSAIC certification process works for manufacturers

The decision behind this topic

For program managers and certification teams, the useful question is not simply what MOSAIC says. The work is sequencing technical and organizational work so late findings do not reset the program. The management decision is what must happen first, what can run in parallel, and what gates market launch. That requires an aircraft-specific record, not a generic interpretation copied into a schedule.

A credible program distinguishes confirmed requirements from assumptions, ties each conclusion to the configuration it covers, and gives unresolved items an owner and a decision date. This is especially important when prior certification work, supplier evidence, or commercial forecasts are being reused in a new U.S. context.

Evidence to put on the table

A practical way to proceed

1. 1

   run an early eligibility and pathway review

2. 2

   create stage gates for evidence, production, and manuals

3. 3

   preserve a decision log for interpretations and changes

The output should be a traceable recommendation with conditions, not an unsupported yes or no. Where evidence is incomplete, show the closure method, cost and schedule exposure, and the event that will change the decision.
