We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Before the accumulation of 15,000 total flight hours, or within 5,000 flight hours after the effective date of this AD, whichever occurs later, do the actions specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD.
(1) Remove the lower passenger door ramp, in accordance with the applicable Bombardier modification summary package specified in Table 1 of this AD.
(2) Do a general visual inspection for any damage and corrosion behind the drainage ramp in the lower portion of the passenger door. If any damage or corrosion is found, before further flight repair in accordance with a method approved by the Manager, New York Aircraft Certification Office, FAA; or Transport Canada Civil Aviation (TCCA) (or its delegated agent).
(3) Apply corrosion inhibitor compound, in accordance with the applicable Bombardier modification summary package specified in Table 1 of this AD.
