Airworthiness Directive · Amendment 39-23182 · Flight controls
Bombardier, Inc., Airplanes
This AD applies to all Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This AD was prompted by reports that the flap system on-board recorder (FSOBR) interfaces with the flap control unit signals and may result in the flap control unit monitors tripping, causing Flap Fail messages and possibly an uncommanded flap movement. This AD requires the disconnection of the FSOBR and prohibits future installation of this system. The FAA is issuing this AD to address the unsafe condition on these products.
For airplanes that have incorporated Bombardier Service Bulletin 604-27-035, Bombardier Service Bulletin 605-27-006, or Bombardier Service Bulletin 650-27-001 as of the effective date of this AD: Within 1,000 flight hours or 14 months, whichever occurs first, after the effective date of this AD, disconnect the FSOBR in accordance with Section 2.B of the Accomplishment Instructions of the applicable service bulletin listed in table 1 to paragraph (g) of this AD.
