What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2018-25- 04, which applied to certain C Series Aircraft Limited Partnership (CSALP) Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2018-25-04 required repetitive inspections for any dislodged blow-out panel in the forward and aft cargo compartments, reporting of the inspection findings, and reinstallation if necessary. This new AD continues to require repetitive inspections, with a revised inspection interval, for affected panels that have not been replaced. This new AD also requires the replacement of affected blow-out panels with redesigned panels, which terminates the inspection requirement. This new AD also revises the applicability by removing certain airplanes. This AD was prompted by reports of dislodged cargo compartment blow-out panels. 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.

Whether AD 2020-09946 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 2020-09946 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.
