## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Honda Aircraft Company, LLC (Honda) Model HA-420 airplanes. This proposed AD was prompted by a report of in-flight smoke and fire that initiated from the windshield heat power wire braid. This proposed AD would require incorporating temporary revisions into the airplane flight manual (AFM) and the quick reference handbook (QRH) that modify procedures for windshield heat operation until the affected windshield assemblies are replaced. The FAA proposes this AD to address the unsafe condition on these products.
