Airworthiness Directive · Amendment 39-17593 · Landing gear
Diamond Aircraft Industries GmbH Airplanes
This AD applies to Diamond Aircraft Industries GmbH Models DA 42, DA 42 NG, and DA 42 M-NG airplanes, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for 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 insufficient clearance between the rod end safety washer and the nose landing gear attachment lever causes the rod end to bend at each gear retraction sequence. 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) and (f)(2) of this AD:
(1) Within 100 hours time-in-service after October 31, 2013 (the effective date of this AD) or 6 calendar months after October 31, 2013 (the effective date of this AD), whichever occurs first, inspect the NLG actuator to identify the part number (P/N) and serial number (S/N). If a NLG actuator P/N X11-0006/2 is installed with a S/N between 0001 and 0155 (inclusive), modify the actuator by replacing the NLG rod end bearing and safety washer with new parts. Follow the INSTRUCTIONS section of Diamond Aircraft Industries GmbH Work Instructions WI-MSB 42-099 and WI-MSB 42NG-035 (co-published as one document), Revision 1, dated May 3, 2013, as specified in the Accomplishments/Instructions paragraph of Diamond Aircraft Industries GmbH Mandatory Service Bulletins MSB 42-099/1 and MSB 42NG-035/1 (co-published as one document), dated May 3, 2013.
(2) As of October 31, 2013 (the effective date of this AD), do not install on any airplane an NLG actuator P/N X11-0006/2 with a S/N between 0001 and 0155 (inclusive), unless the actuator has been modified following the INSTRUCTIONS section of Diamond Aircraft Industries GmbH Work Instructions WI-MSB 42-099 and WI-MSB 42NG-035 (co-published as one document), Revision 1, dated May 3, 2013, as specified in the Accomplishments/Instructions paragraph of Diamond Aircraft Industries GmbH Mandatory Service Bulletins MSB 42-099/1 and MSB 42NG-035/1 (co-published as one document), dated May 3, 2013.
