## Abstract

The FAA is superseding Airworthiness Directive (AD) 2019-22- 07, which applied to all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2019-22-07 required revising the existing airplane flight manual (AFM) to include a limitation and an abnormal operating procedure for the Automatic Flight Control System (AFCS). This AD requires revising the existing AFM and adding airplanes to the applicability. This AD was prompted by a finding that the limitation and abnormal operating procedure did not include reference to a certain mode. The FAA is issuing this AD to address the unsafe condition on these products.
