Effective Date (a) This airworthiness directive (AD) becomes effective December 30, 2008. Affected ADs (b) None. Applicability (c) This AD applies to Bombardier Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, serial numbers 10003 through 10216 inclusive; and Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers 15001 through 15040 inclusive; certificated in any category. Subject (d) Air Transport Association (ATA) of America Code 56: Windows. Reason (e) The mandatory continuing airworthiness information (MCAI) states: There have been several incidents of shorting and sparks due to de-icing fluid ingress into the cockpit of CL-600-2C10 and CL-600- 2D24 aircraft. De-icing fluid can enter between the windshields and side windows, leading to possible damage to the electrical components and wires as it comes into contact with cockpit floodlight electrical connections. De-icing fluid in contact with cockpit floodlight electrical connections can result in possible arcing and fire. The actions to address the unsafe condition include performing a leak test, applying sealant between the windshields and side windows, and doing related investigative and corrective actions. The related investigative action is performing a leak test after applying sealant. The related corrective action is contacting Bombardier for repair instructions and doing the repair. Actions and Compliance (f) Unless already done, do the following actions. (1) Within 450 flight hours after the effective date of this AD: Perform a leak test in accordance with Part A of the Accomplishment Instructions of Bombardier Alert Service Bulletin A670BA-56-002, Revision A, dated February 26, 2008. (2) If leakage is detected in the leak test performed in accordance with paragraph (f)(1) of this AD: Prior to further flight, apply sealant between the windshields and side windows and do all applicable related investigative and corrective actions in accordance with Part B of the Accomplishment Instructions of Bombardier Alert Service Bulletin A670BA-56-002, Revision A, dated February 26, 2008. Do all applicable related investigative and corrective actions before further flight. (3) If there is no leakage detected in the leak test performed in accordance with paragraph (f)(1) of this AD: Within 6 months or 2,000 flight hours after the effective date of this AD, whichever comes first, apply sealant between the windshields and side windows and do all applicable related investigative and corrective actions before further flight in accordance with Part B of the Accomplishment Instructions of Bombardier Alert Service Bulletin A670BA-56-002, Revision A, dated February 26, 2008. Do all applicable related investigative and correctiveactions before further flight.
