What to do
Operators of affected Honda HA-420 airplanes must insert the temporary revision into the airplane flight manual by May 29, 2018, and perform pilot checks for defective power brake valves before every flight and landing. If a defective valve is found, it must be replaced with the improved part number HJ1-13243-101-009. Comments on this AD must be submitted by July 9, 2018. Maintaining compliance records as specified is also required.
Summary
FAA Airworthiness Directive 2018-11-05 is a final rule superseding AD 2018-06-10 and applies to certain Honda Aircraft Company LLC Model HA-420 airplanes. It addresses an unsafe condition related to faulty power brake valves that can cause degraded braking performance and reduced directional control during ground operations and landing deceleration. This AD corrects a typographical error in the serial number applicability from the previous AD and retains the required actions including inserting a temporary revision into the airplane flight manual and replacing defective power brake valves.
What changed
This AD corrects the serial number applicability error found in the previous AD 2018-06-10 and the associated service bulletin by properly defining the affected Model HA-420 airplane serial numbers. It retains the original requirements of incorporating a temporary revision into the airplane flight manual and replacing faulty power brake valves when detected. Additionally, it adds airplanes to the applicability section to ensure all affected aircraft are covered.
Why it matters
This AD is critical for aviation professionals because it ensures accurate identification of affected aircraft, preventing potential safety risks due to faulty power brake valves. Operators and maintenance personnel must be aware of the corrected applicability to maintain compliance and ensure safe braking performance. Proper adherence to this AD helps avoid degraded braking and loss of directional control during critical phases of ground operations and landing.
