Superseded. A later AD replaced this one: AD 2008-09-24 R1. Comply with the one in force.
This AD applies to all Bombardier Model DHC-8-400, DHC-8-401, and DHC-8-402 airplanes, certificated in any category, all serial numbers.
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:
Unless already done, do the following actions.
(1) For all airplanes: Within 60 days after the effective date of this AD, or before December 16, 2008, whichever occurs first, revise the ALS of the Instructions for Continued Airworthiness to incorporate the CDCCLs specified in Dash 8 Q400 (Bombardier) Temporary Revisions (TRs) ALI-55, dated April 19, 2006; and ALI-56, dated April 19, 2006; to Part 2, “Airworthiness Limitations Items,” of the Bombardier Dash 8 Q400 Maintenance Requirements Manual (MRM) PSM 1-84-7.
Note 1: The actions required by paragraph (f)(1) of this AD may be done by inserting a copy of the applicable TR into the maintenance requirements manual. When the TR has been included in the general revision of the maintenance program, the general revision may be inserted into the maintenance requirements manual, provided the relevant information in the general revision is identical to that in the applicable TR, and the temporary revision may be removed.
(2) After accomplishing the actions specified in paragraph (f)(1) of this AD, no alternative CDCCLs may be used unless the CDCCLs are part of a later revision of Part 2, Revision 4, dated October 30, 2003, of the Bombardier Dash 8 Q400 MRM PSM 1-84-7, Revision 4, that is approved by the Manager, New York Aircraft Certification Office (ACO), FAA, or Transport Canada Civil Aviation (or its delegated agent); or unless the CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g)(1) of this AD.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
