This AD applies to Bombardier, Inc. Model DHC-8-400, -401, and -402 airplanes, certificated in any category, serial numbers 4001, 4003 and subsequent.
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.

When this TR has been included in the general revisions of Part 1 of the Maintenance Review Board Report of the Bombardier Q400 Dash 8 Maintenance Requirements Manual, PSM 1-84-7, the general revisions may be inserted in Part 1 of the Maintenance Review Board Report of the Bombardier Q400 Dash 8 Maintenance Requirements Manual, PSM 1-84-7, provided the relevant information in the general revisions is identical to that in Bombardier TR MRB-45, dated October 6, 2009.
After accomplishing the revision required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i) of this AD.
