Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
This AD applies to Bombardier Model CL-600-2B19 (Regional Jet series 100 & 440) airplanes, certificated in any category, serial numbers 7003 through 7067 inclusive, 7069 through 7165 inclusive, 7167 through 7169 inclusive, and 7171 through 7188 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires installing additional shielding of the hydraulic lines in the wing box area. This AD results from the determination that the additional hydraulic line shields will protect the lines from possible impact by tire debris if the tire tread fails. We are issuing this AD to prevent damage to the hydraulic lines and subsequent leakage from the two hydraulic systems, which could result in loss of braking capability on the affected side of the airplane, asymmetrical braking, and reduced directional control--particularly during a rejected takeoff.
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 24 months after the effective date of this AD, install additional shielding of the hydraulic lines in the wing box area, by doing all the actions specified in the Accomplishment Instructions of Bombardier Service Bulletin 601R-57-021, Revision D, dated July 11, 2005.
(g) Installations accomplished before the effective date of this AD according to Bombardier Service Bulletin 601R-57-021, Revision “B,” dated July 18, 2001; or Revision “C,” dated February 23, 2004; are considered acceptable for compliance with the corresponding action specified in this AD.
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.
