Airworthiness Directive · Amendment 39-13372 · Bombardier Model CL-600-2C10 (Regional Jet Series 700 & 701) Series Airplanes
Bombardier Model CL-600-2C10 (Regional Jet Series 700 & 701) Series Airplanes
Model CL-600-2C10 (Regional Jet Series 700 & 701) series airplanes, serial numbers 10004 through 10119 inclusive; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2C10 (Regional Jet Series 700 & 701) series airplanes, that currently requires a revision to the Airplane Flight Manual (AFM) to prohibit operations into known or forecast icing conditions under certain conditions. That AD also requires an inspection to detect damage of the wing anti-ice (WAI) ducts to determine if the external shrouds of the ducts are open or cracked, and replacement of any damaged duct with a new duct or a duct with the same part number, and an optional terminating action. This amendment requires accomplishment of the previously optional terminating action for the AFM revision and inspection. The actions specified by this AD are intended to prevent the WAI ducts from collapsing, cracking, or rupturing, which could cause leakage of hot air in the under-floor pressurized area of the fuselage when the anti- ice system is turned on. Such leakage of hot air results in insufficient heat for the anti-ice system and consequent aerodynamic degradation. This action is intended to address the identified unsafe condition.
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.
