Airworthiness Directive 2023-24-08
one-timeAirworthiness Directives; Bombardier, Inc., Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports that the nose wheel steering selector valve (SSV) can be slow to deactivate under low temperature conditions. This AD requires replacing the affected SSV with a re-designed SSV that has an improved response time. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2023-24-08 applies to
Applies to airplanes identified in Bombardier Service Bulletins 700-32-044 Rev 01, 700-32-6021 Rev 01, 700-32-6507 Rev 01 (all dated December 7, 2022, for Model BD-700-1A10), and 700-1A11-32-031 Rev 01, 700-32-5021 Rev 01, 700-32-5507 Rev 01 (all dated December 7, 2022, for Model BD-700-1A11)
Whether AD 2023-24-08 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.
