Airworthiness Directives; Honda Aircraft Company LLC Airplanes

FAA / Federal Register · 2026-10606

The FAA is adopting a new airworthiness directive (AD) for certain Honda Aircraft Company LLC (Honda) Model HA-420 airplanes. This AD was prompted by a report of tool damage to multiple locations on the interior fuselage skin fiber and the omission of certain service material from the Airworthiness Limitations Section (ALS) of the maintenance manual. This AD requires incorporating certain material into the ALS of the existing maintenance manual or instructions for continued airworthiness (ICA) and the existing maintenance or inspection program, as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
