Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires doing repetitive inspections for fractures and cracks of the links of the aileron power control unit (PCU); replacing any fractured/cracked link; and doing applicable related investigative and corrective actions, if necessary. This AD is prompted by reports indicating that the links of the aileron PCU have failed. We are issuing this AD to prevent failure of both links of the aileron PCU, which could result in reduced lateral control of the airplane.
