What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 airplanes. This AD was prompted by a report indicating that the clearance between therapeutic flexible oxygen hoses and electrical harnesses may be non-compliant to design requirements, and that positive separation mechanisms and appropriate protective barriers may not have been installed in accordance with the applicable installation standards. This AD requires a detailed inspection of the therapeutic flexible oxygen hose for damage and protection, and the electrical harnesses for damage; a detailed inspection for the clearance between the therapeutic oxygen rigid tube to oxygen hose elbow fitting (also referred to as elbow fitting), if applicable, and the nearest electrical harness, and between the therapeutic flexible oxygen hose and electrical harness; and applicable related investigative and corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.

Applicability limited to airplanes identified in Bombardier Service Bulletin 700-35-016, dated June 12, 2024; Bombardier Service Bulletin 700-35-6006, dated June 12, 2024; and Bombardier Service Bulletin 700-35-6503, dated June 12, 2024.

Whether AD 2025-16-07 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 2025-16-07 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.
