Airworthiness Directive 2025-07-11
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 of engine-driven pump hydraulic pressure hoses for hydraulic systems number 1 and 2 chafing against the pylon in the aft equipment bay. This AD requires an inspection of the engine-driven pump pressure hoses for any damage and minimum clearance between the engine-driven pump hydraulic pressure hose and case drain, suction pressure hose, and surrounding pylon structure; and corrective actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2025-07-11 applies to
Whether AD 2025-07-11 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.
