Airworthiness Directive 2026-07736
recurringAirworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
What this AD requires
The FAA is superseding Airworthiness Directive (AD) 2025-22- 02, which applied to certain MHI RJ Aviation ULC (type certificate previously held by Bombardier, Inc.) Model CL-600-2C10 (Regional Jet Series 700, 701 &702), CL-600-2C11 (Regional Jet Series 550), CL-600- 2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2025-22-02 required repetitive torque checks of the horizontal stabilizer (H-stab) anti-yaw steady fitting block bolts. Since the FAA issued AD 2025-22- 02, it was determined that additional actions must be done to address the unsafe condition. This AD continues to require the actions in AD 2025-22-02 and requires replacing the H-stab anti-yaw steady fitting block hardware. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2026-07736 applies to
Applicability determined by aircraft identified in Transport Canada AD CF-2025-38, effective August 19, 2025. Model designations correspond to marketing series: CL-600-2C10 = Regional Jet Series 700/701/702; CL-600-2C11 = Regional Jet Series 550; CL-600-2D15 = Regional Jet Series 705; CL-600-2D24 = Regional Jet Series 900; CL-600-2E25 = Regional Jet Series 1000.

Whether AD 2026-07736 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.
