Airworthiness Directives; C Series Aircraft Limited Partnership (CSALP) (Type Certificate Previously Held by Bombardier, Inc.) Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain C Series Aircraft Limited Partnership (CSALP) Model BD-500-1A10 and BD- 500-1A11 airplanes. This AD was prompted by reports of dislodged cargo compartment blowout panels. This AD requires repetitive inspections for any dislodged blow-out panel in the forward and aft cargo compartments, reporting of the inspection findings, and reinstallation if necessary. We are 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.

Type certificate previously held by Bombardier, Inc. Applies only to airplanes equipped with blow-out panel P/N D762213-503, D762216-505, or D762209-503: Model BD-500-1A10 airplanes, serial numbers 50001 and subsequent; Model BD-500-1A11 airplanes, serial numbers 55001 and subsequent.

Whether AD 2018-26473 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 2018-26473 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.
