AD 2007-26-25 Airworthiness Directives; DG Flugzeugbau GmbH Model DG-500MB Gliders

This AD applies to Model DG-500MB gliders, all serial numbers, certificated in any category.

Unless already done, within 90 days after February 7, 2008 (the effective date of this AD): (1) Secure the connection between the spindle drive “Stross BSA10” and the spindle drive motor following DG Flugzeugbau GmbH Working instruction No. 1, dated January 23, 2006, as referenced in DG Flugzeugbau GmbH Technical Note No. 843-24, dated January 31, 2006. (2) Replace the fork 8M233/1 from the spindle drive with the strengthened fork 8M233“f”; replace the bearing support with the modified support 8M229“e”; and secure the spindle drive fork between the spindle drive “Stross BSA10” and the spindle drive motor following DG Flugzeugbau GmbH Working instruction No. 2, dated January 30, 2006, as referenced in DG Flugzeugbau GmbH Technical Note No. 843-24, dated January 31, 2006; DG Flugzeugbau GmbH Drawing 5M210, Spindle drive Stross BSA 10 assembly, issued: January 22, 2003, revised: May 19, 2006; and DG Flugzeugbau GmbH Drawing 5M211, Spindle drive Stross BSA 10 assembly with strengthened fork 8M233“f”, issued: January 23, 2006. Note 1: We recommend that you insert and update the new Flight Manual pages 0.1, 0.3, 0.4, 2.8, 3.7, 3.8, 4.1, 4.25, 4.26; the new Maintenance Manual pages 1, 2, 3, 4, 5, 42, 49, 68, 89, 89a, 93, and Enclosure 1; and the new Repair Manual pages 1, 2, 7, and 8 following DG Flugzeugbau GmbH Technical Note No. 843-24, dated January 31, 2006. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: (1) The service information specifies a one-time inspection of the fork and requires replacement if cracks are found. This AD requires mandatory replacement of these parts with redesigned parts. The FAA believes mandatory replacement rather than inspection will prevent failure of these parts in the future. (2) The MCAI requires, for gliders certificated for operation in Germany, to have the pages in the flight, maintenance, and repair manuals exchanged.We have determined that the exchange of these pages is outside the scope of what is needed to correct the unsafe condition for gliders certificated for operation in the United States. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Greg Davison, Glider Program Manager, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4130; fax: (816) 329-4090. 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. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. ), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
