## Abstract

We are superseding Airworthiness Directive (AD) 2018-11-05 for certain Honda Aircraft Company LLC (Honda) Model HA-420 airplanes. AD 2018-11-05 required incorporating a temporary revision into the airplane flight manual (AFM) and replacing the faulty power brake valve (PBV) upon condition. We issued AD 2018-11-05 as a short-term action to address the immediate need to detect and replace a faulty PBV. This AD retains the actions required in AD 2018-11-05 and requires replacing the faulty PBV with the improved part. We are issuing this AD to address the long-term corrective action and address the unsafe condition on these products.
