## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 series airplanes, that currently requires repetitive ultrasonic inspection to detect damage of the actuator lugs of the flight spoiler center hinge; and corrective action, if necessary. This amendment mandates the previously optional terminating action by requiring replacement of the flight spoilers with new improved spoilers. The actions specified by this AD are intended to prevent uncommanded deployment of a flight spoiler, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
