Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

Короткий зміст

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.
