Airworthiness Directive 2023-17774
one-timeAirworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by a report from the supplier of a manufacturing quality escape in which some sensing elements were manufactured with insufficient salt fill. This could result in an inability to detect hot bleed air leaks. This AD requires, depending on airplane serial number, reviewing the airplane maintenance records for affected bleed leak detection system sensing elements, testing the sensing elements, replacing those that fail, and witness marking those that pass, as specified in a Transport Canada AD, which is incorporated by reference. This AD also prohibits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2023-17774 applies to
Applies to airplanes as identified in Transport Canada AD CF-2022-13R1, dated April 18, 2023.
Whether AD 2023-17774 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:
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.
