Is AD 2020-03-10 a recurring Airworthiness Directive?

Yes — AD 2020-03-10 requires a repetitive inspection every 36 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2020-03-10 apply to?

AD 2020-03-10 applies to Boeing — models 737. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; The Boeing Company Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for The Boeing Company Model 737 series airplanes, except for Model 737-100, - 200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports of separation of the lower aft wing-to-body fairing panel 194E ("fairing panel 194E") during flight, due to worn or damaged nutplates on the support structure. This AD requires repetitive inspections for discrepancies of fairing panel 194E, wheel well panel 193D, and support structure, and related investigative and corrective actions if necessary. This AD also requires rework of the panels and support structure, which terminates the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 36 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Models737

Applies to all Model 737 series airplanes except Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. Installation of Supplemental Type Certificate (STC) ST00830SE does not affect the ability to accomplish the actions required by this AD; for airplanes with STC ST00830SE installed, a change-in-product alternative method of compliance (AMOC) approval request is necessary.

Whether AD 2020-03-10 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 2020-03-10 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.
