Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding Airworthiness Directive (AD) 2013-16-08 for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD 2013-16-08 required inspection of the main landing gear (MLG) retraction actuator components; corrective actions if necessary; and, for certain retraction actuators, installation of a new jam nut. This new AD continues to require those actions. This AD was prompted by a determination that a certain part was incorrectly identified in a certain section of AD 2013-16-08. We are issuing this AD to prevent disconnection of the MLG retraction actuator, which could result in extension of the MLG without damping, and consequent structural damage and collapse of the MLG during landing.
