Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes

FAA / Federal Register · 2026-07736

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.
