Active advisory guidance
Plain-English Explainer
The FAA circular provides an acceptable route for demonstrating hardware development assurance. Its application is determined by equipment function and the project’s certification basis. An inverter’s airborne digital control hardware may need assurance evidence beyond electrical performance tests; the circular does not certify an inverter or establish its installation approval.
