MOSAIC options for Part 23 manufacturers

The decision behind this topic

For Part 23 aircraft manufacturers, the useful question is not simply what MOSAIC says. The work is evaluating a lighter-weight market path without confusing certification bases. The management decision is whether MOSAIC complements the existing product line or creates avoidable complexity. 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

   protect the approved baseline from uncontrolled cross-program changes

2. 2

   model channel and support implications

3. 3

   document why each item of evidence applies to the MOSAIC candidate

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.
