AD 2008-13-09 Airworthiness Directives; Bombardier Model DHC-8-102, DHC-8-103, DHC-8-106, DHC-8-201, DHC-8-202, DHC-8-301, DHC-8-311, and DHC-8-315 Airplanes

Models named: DHC-8-102, DHC-8-103, DHC-8-106, DHC-8-201, DHC-8-202, DHC-8-301, DHC-8-311, DHC-8-315. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to all Bombardier Model DHC-8-102, DHC-8-103, DHC-8-106, DHC-8-201, DHC-8-202, DHC-8-301, DHC-8-311, and DHC-8-315 airplanes, certificated in any category, all serial numbers. Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (g) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.

Unless already done, do the following actions. (1) 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 fuel system limitations tasks identified in the de Havilland temporary revisions (TRs) to Part 2, “Airworthiness Limitations List,” of the Dash 8 Series Maintenance Program Manuals (“the MPMs”). The TRs are listed in Table 1 of this AD. For the tasks identified in the TRs, the initial compliance times start at the later of the applicable “Threshold” and “Grace Period” times specified in Table 2 of this AD, and the repetitive limitation tasks must be accomplished thereafter at the interval specified in the TRs, except as provided by paragraphs (f)(2), (f)(3), (f)(4), and (g)(1) of this AD. Table 1—Temporary Revisions Model de Havilland TR MPM DHC-8-102, DHC-8-103, and DHC-8-106 airplanes AWL-110, dated August 31, 2007 Dash 8 Series 100 MPM, Product Support Manual (PSM) 1-8-7, Part 2, “Airworthiness Limitations List”. DHC-8-201, and DHC-8-202 airplanes AWL 2-43, dated August 31, 2007 Dash 8 Series 200 MPM, PSM 1-82-7, Part 2, “Airworthiness Limitations List”. DHC-8-301, DHC-8-311, and DHC-8-315 airplanes AWL 3-109, dated August 31, 2007 Dash 8 Series 300 MPM, PSM 1-83-7, Part 2, “Airworthiness Limitations List”. Table 2—Initial Inspections Description Compliance time (whichever occurs later) Threshold Grace period Tasks with 6,000 flight hours/36 month intervals Before the accumulation of 6,000 total flight hours, or within 36 months since new, whichever occurs first Within 2,000 flight hours or 12 months after the effective date of this AD, whichever occurs first. Tasks with 18,000 flight hours/108 month intervals Before the accumulation of 18,000 total flight hours, or within 108 months since new, whichever occurs first Within 6,000 flight hours or 36 months after the effective date of this AD, whichever occurs first. Tasks with 72,000 flight hours/36 year intervals Before the accumulation of 72,000 total flight hours, or within 36 years since new, whichever occurs first Within 600 flight hours or 3 months after the effective date of this AD, whichever occurs first. Note 2: The actions required by paragraph (f)(1) of this AD may be done by inserting a copy of the applicable TR listed in Table 1 of this AD into the ALS of the applicable MPM listed in Table 1 of this AD. When the applicable TR has been included in general revisions of the applicable MPM, the general revisions may be inserted in the MPM, provided the relevant information in the general revision is identical to that in the applicable TR. (2) For those tasks with 6,000 flight hours/36 month limitation task intervals: For airplanes that have accumulated 4,000 total flight hours or more, or 24 months or more since new, as of the effective date of this AD, do the initial limitation tasks within 2,000 flight hours or 12 months after the effective date of this AD, whichever occurs first. Thereafter, repeat the limitation tasks at intervals not to exceed 6,000 flight hours or 36 months, whichever occurs first. (3) For those tasks with 18,000 flight hours/108 month limitation task intervals: For airplanes that have accumulated 12,000 total flight hours or more, or 72 months or more since new, as of the effective date of this AD, do the initial limitation tasks within 6,000 flight hours or 36 months after the effective date of this AD, whichever occurs first. Thereafter, repeat the limitation tasks at intervals not to exceed 18,000 flight hours or 108 months, whichever occurs first. (4) After accomplishing the actions specified in paragraphs (f)(1), (f)(2), and (f)(3) of this AD, no alternative inspections/limitation tasks or inspection/limitation task intervals may be used unless the inspections/limitation tasks or inspection/limitation task intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g)(1) of this AD. FAA AD Differences Note 3: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, New York ACO, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.
