Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to all Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This action requires repetitive inspections of the left and right engine throttle control gearboxes for wear, and corrective action if necessary. This action is necessary to prevent excessive wear of the gearboxes and subsequent movement or jamming of the engine throttle; movement of the throttle towards the idle position brings it close to the fuel shut-off switch, which could result in an in-flight engine shutdown. This action is intended to address the identified unsafe condition.
