Is AD 2026-04465 a recurring Airworthiness Directive?

Yes — AD 2026-04465 requires a repetitive inspection every 200 hours. Next-due depends on the aircraft's time in service.

Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2023-23- 02, which applied to all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440), CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2023-23-02 required, for certain airplanes, revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations; and accomplishing certain aircraft maintenance manual (AMM) tasks and corrective actions following short-term or long-term storage. Since the FAA issued AD 2023-23-02, additional power control unit (PCU) disconnect findings show that the task intervals must be reduced to allow earlier detection of potential single PCU disconnect cases. This AD continues to require certain actions in AD 2023-23-02 and requires repetitive operational checks of the rudder PCUs and repetitive operational tests of the elevator PCUs. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 200 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 2026-04465 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 2026-04465 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.
