Airworthiness Directive · Amendment 39-17762 · Electric power
Diamond Aircraft Industries GmbH Airplanes
This AD applies to Diamond Aircraft Industries GmbH Models DA 42 NG and DA 42 M NG airplanes, all serial numbers certificated in any category, except those that have incorporated Supplemental Type Certificate (STC) SA02725NY (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/286A29A0C46D66048625764900624649?OpenDocument&Highlight=sa02725ny).
Note 1 to paragraph (c) of this AD: STC SA02725NY uses different electrical system architecture and the unsafe condition addressed in this AD does not apply to that system.
We are adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH Models DA 42 NG and DA 42 M-NG airplanes. 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 the failure of the alternator indication system to indicate warning when one alternator is inoperative. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions as specified in paragraphs (f)(1) through (f)(3) of this AD, including all subparagraphs:
(1) For all DA 42 NG airplanes: Within the next 12 months after April 7, 2014 (the effective date of this AD), install Secondary Configuration Card part number (P/N) 010-12074-02 “Additional ALTN FAIL trigger” and System Software P/N 010-00670-10 following the Accomplishment/Instructions in Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 42NG-003/13, dated October 11, 2013; or the Accomplishment/Instructions in Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 42NG-003/12, dated July 8, 2013.
(2) For DA 42 M-NG airplanes, serial numbers (S/Ns) 42.339, 42.MN001 through 42.MN0026, and all S/Ns modified through Optional Service Bulletin (OSB) 42-081, using Work Instruction (WI) OSB-42-081 up to Revision 1 inclusive: Within the next 100 hours time-in-service after April 7, 2014 (the effective date of this AD) or within the next 12 months after April 7, 2014 (the effective date of this AD), whichever occurs first:
(i) Install GEA Alternator fail control cable P/N D62-2510-97-00-SB following the Instructions in Diamond Aircraft Industries GmbH Work Instruction WI-MSB 42MNG-006, dated July 8, 2013, as specified in the Accomplishments/Instructions in Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 42MNG-006, July 8, 2013; and
(ii) Install Secondary Configuration Card P/N 010-12074-02 “Additional ALTN FAIL trigger” and System Software P/N 010-00670-10 following the Accomplishment/Instructions in Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 42NG-003/13, dated October 11, 2013; or the Accomplishment/Instructions in Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 42NG-003/12, dated July 8, 2013.
(3) For all airplanes: As of April 7, 2014 (the effective date of this AD), do not install on any airplane System Software prior to P/N 010-00670-10.
