## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, that requires replacement of landing gear control handle components with new, improved components. This action is necessary to prevent an inability to lower or retract the landing gear using the landing gear control handle, which could result in use of Emergency Procedures using the landing gear manual release. This action is intended to address the identified unsafe condition.
