Airworthiness Directives; Honda Aircraft Company LLC Airplanes

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2021-22-12 for certain Honda Aircraft Company LLC (Honda) Model HA-420 airplanes. AD 2021-22-12 required removing and cleaning the inner diameter of the flap control pushrod assemblies and repetitively applying corrosion inhibiting compound (CIC) to this area. Since the FAA issued AD 2021- 22-12, new flap control pushrods have been approved that are more corrosion resistant and do not require repetitive CIC applications. In addition, referenced service material has been updated to a new revision that includes redesigned replacement flap control pushrod assemblies that have been modified to prevent interference with adjacent parts. This AD retains the requirements of AD 2021-22-12 and requires replacing the flap control pushrod assemblies with improved design pushrod assemblies for all airplanes affected by AD 2021-22-12, as well as for other airplanes not affected by AD 2021-22-12. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Group 1 airplanes: serial numbers 42000153 through 42000158 and 42000160 through 42000206. Group 2 airplanes: serial numbers 42000211, 42000212, and 42000215 through 42000287.

Whether AD 2026-06-71 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2026-06-71 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
