Airworthiness Directive · Amendment 39-15828 · Bombardier Model CL-215-6B11 (CL-215T Variant) and CL-215-6B11 (CL-415 Variant) Airplanes
Bombardier Model CL-215-6B11 (CL-215T Variant) and CL-215-6B11 (CL-415 Variant) Airplanes
This AD applies to the following airplanes, certificated in any category:
(1) Bombardier Model CL-215-6B11 (CL-215T variant) airplanes, serial numbers 1056 through 1125 inclusive, and
(2) Bombardier Model CL-215-6B11 (CL-415 variant) airplanes, serial numbers 2001 through 2990 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-215-6B11 (CL-215T variant) and CL-215-6B11 (CL-415 variant) airplanes. This AD requires repetitive inspections for contamination of grease, bearing wear checks, grease applications of the rudder lower torque tube upper bearing, and a rudder upper hinge gap check; and related investigative and corrective actions if necessary. This AD results from a report of corrosion on the rudder lower torque tube upper bearing. We are issuing this AD to detect and correct corroded bearings which could lead to hinge deformation, and could result in a rudder jam and consequent reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 6 months after the effective date of this AD, do a detailed inspection for contamination of grease, a bearing wear check, and grease application of the rudder lower torque tube upper bearing, and do a rudder upper hinge gap check, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 215-3151, dated May 5, 2008 (for 215T variant airplanes); or Bombardier Service Bulletin 215-4394, dated May 5, 2008 (for 415 variant airplanes); as applicable. Do all related investigative and corrective actions before further flight in accordance with the service bulletin, as applicable. Repeat the detailed inspection thereafter at intervals not to exceed 6 months.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
Although Bombardier Service Bulletin 215-3151, dated May 5, 2008; and Bombardier Service Bulletin 215-4394, dated May 5, 2008; specify to submit certain information to the manufacturer, this AD does not include that requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
