Airworthiness Directives; Honda Aircraft Company LLC Airplanes

We are superseding Airworthiness Directive (AD) 2018-06-10 for certain Honda Aircraft Company LLC Model HA-420 airplanes. AD 2018-06- 10 required incorporating a temporary revision into the airplane flight manual and replacing faulty power brake valves upon condition. This AD retains the actions required in AD 2018-06-10 and adds airplanes to the Applicability section. This AD was prompted by an inadvertent mistake in the serial number applicability (both in the service bulletin and in the AD). We are issuing this AD to address the unsafe condition on these products by correcting the inadvertent serial number error.
