Airworthiness Directive · Amendment 39-17615 · Fuselage
Bombardier, Inc. Airplanes
This AD applies to Bombardier, Inc. Model CL-215-6B11 (CL-415 Variant) airplanes, certificated in any category, serial numbers 2001 through 2076 inclusive.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-215-6B11 (CL-415 Variant) airplanes. This AD requires replacing the panel assembly of the main distribution center (MDC) rack. This AD was prompted by findings of chafed power wires due to flexing of the MDC rack panel. We are issuing this AD to prevent damage to power wires, which could cause simultaneous loss of systems such as electrical power, pilot indications, and caution/advisory lighting systems, which are essential for safe flight.
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 13 months after the effective date of this AD: Replace the existing MDC rack panel assembly with a new rack panel assembly, in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin 215-A4436, Revision 1, dated February 2, 2012. A note in the Accomplishment Instructions section of Bombardier Alert Service Bulletin 215-A4436, Revision 1, dated February 2, 2012, instructs operators to contact Bombardier “if any deviation exists” in accomplishing the service bulletin; however, any deviation from the instructions provided in the service bulletin must be approved as an alternative method of compliance (AMOC) under paragraph (i)(1) of this AD.
