What 14 CFR Part 22 means for a MOSAIC aircraft program

The decision behind this topic

For engineering and airworthiness organizations, the useful question is not simply what MOSAIC says. The work is translating Part 22 obligations into owned work packages. The management decision is how the company will demonstrate and maintain conformity for the declared aircraft. 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

   build a clause-level responsibility matrix

2. 2

   identify evidence that can be reused and evidence that needs translation

3. 3

   connect declaration readiness to production-system readiness

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.
