The MCAI describes the unsafe condition as:

(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 corrective actions before further flight.
(4) A leak test and application of sealant are also acceptable for compliance with the requirements of paragraphs (f)(1), (f)(2), and (f)(3) of this AD if done before the effective date of this AD in accordance with Bombardier Alert Service Bulletin A670BA-56-002, dated January 7, 2008.
