DG Flugzeugbau GmbH Model DG-1000T Gliders
This AD applies to DG-1000T gliders, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:
Within the next 60 days after October 26, 2007 (the effective day of this AD), unless already done, do the following actions:
(1) Replace the Digital Indicating System (DEI-NT) unit with an updated unit that incorporates software version V1.5, and replace the control unit with an updated unit that incorporates software version V1.9 following DG-Flugzeugbau GmbH Technical Note No. 1000/09, EASA approved December 12, 2006.
(2) Insert the new Flight Manual pages 0.1, 0.5, 7.14, and 7.15 and the new Maintenance Manual pages 0.1, 0.3, 0.6, 0.10, 1.22, and 1.23, issued October 2006 marked with TN1000/09, and add Diagram 15a into your maintenance program (maintenance manual) following DG-Flugzeugbau GmbH Technical Note No. 1000/09, EASA approved December 12, 2006.
(3) Prior to further flight after the action required by paragraph (f)(1) of this AD, do not install a DEI-NT or control unit in any DG-1000T airplane, unless it incorporates the software versions required in this AD.
Note 1: The referenced DG-Flugzeugbau GmbH Technical Note No. 1000/09, EASA approved December 12, 2006, also includes instructions for replacement of the fuel cock, which is not required by this AD.
Note 2: As specified in the flight manual, the glider can only be operated in the non-powered configuration without the DEI-NT installed. Engine operation is not possible.
Note 3: This AD differs from the MCAI as follows: No differences.
