What to do
Operators must replace the left and right fixed control rods and lever assemblies within 9200 flight hours or 5 years from the original AD effective date of 2014-12-23 if not already done. Additionally, within 8800 flight hours from the issuance of Revision 1, a detailed visual inspection and re-torqueing of self-locking nuts must be performed following Bombardier SB 670BA-27-062 Revision E or later approved revisions.
Summary
The Canadian Airworthiness Directive CF-2014-44R2 addresses the elevator control system disconnect issue on Bombardier Inc. Model CL-600-2C10, CL-600-2D15, and CL-600-2D24 aeroplanes. This directive mandates replacement and inspection of elevator lever assemblies and control rods to prevent uncommanded elevator movements that could compromise aircraft controllability and structural integrity.
What changed
CF-2014-44R2 revises the previous AD CF-2014-44R1 by correcting an editorial error related to the revision date of Bombardier Service Bulletin 670BA-27-062, Revision D. It continues to require the replacement of elevator lever assemblies and control rods and adds detailed visual inspections and re-torqueing of self-locking nuts on the elevator control linkages.
Why it matters
This directive is critical for maintaining safe flight control operations by preventing elevator control system failures that could lead to reduced aircraft controllability and potential structural damage. Compliance ensures continued airworthiness and reduces the risk of in-flight control anomalies, which is essential for operators, maintenance organizations, and regulatory compliance teams.
