We are adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH Models DA 42, 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 excessive voids in the adhesive joint between the center wing spars and the upper center wing skins. This condition could cause the wing to fail, which could result in loss of control of the airplane. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions:
(1) Within the next 100 hours time-in-service (TIS) after October 11, 2012 (the effective date of this AD) or within the next 3 months after October 11, 2012 (the effective date of this AD), whichever occurs first, inspect the adhesive joint between the center wing spars and the upper center wing skin following Diamond Aircraft Industries GmbH Work Instruction WI-MSB-42-092, WI-MSB-42NG-22, dated May 20, 2011, as specified in Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 42-092, MSB 42NG-022, dated May 20, 2011.
(2) Within 30 days after the inspection required in paragraph (f)(1) of this AD, using Appendix A of Diamond Aircraft Industries GmbH Work Instruction WI-MSB-42-092, WI-MSB-42NG-22, dated May 20, 2011, report the results of the inspection to Diamond Aircraft Industries GmbH at the address in paragraph (i)(3) of this AD.
(3) If, during the inspection required in paragraph (f)(1) of this AD, voids are detected that exceed the criteria specified in Diamond Aircraft Industries GmbH Work Instruction WI-MSB-42-092, WI-MSB-42NG-22, dated May 20, 2011, before further flight, repair the airplane following Diamond Aircraft Industries GmbH Work Instruction WI-MSB-42-092, WI-MSB-42NG-22, dated May 20, 2011, as specified in Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 42-092, MSB 42NG-022, dated May 20, 2011.
(4) For the purpose of compliance with paragraph (f)(3) of this AD, a single positioning flight is allowed to a location where the repair can be done following the provisions specified in Section III.1 of Diamond Aircraft Industries GmbH Work Instruction WI-MSB-42-092, WI-MSB-42NG-22, dated May 20, 2011.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
