ACTION: Final rule. SUMMARY: 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.)

AD 2025-22-02 required repetitive torque checks of the horizontal stabilizer (H-stab) anti-yaw steady fitting block bolts.

The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective May 26, 2026.
