Airworthiness Directive · Amendment 39-17405 · Landing gear
Diamond Aircraft Industries GmbH Airplanes
This AD applies to Diamond Aircraft Industries GmbH Models DA 42, DA 42 M-NG, and DA 42 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 M-NG, and DA 42NG 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 overextension of the main landing gear (MLG) shock absorber that could lead to the MLG jamming in the gear bay and result in damage to the aircraft or occupant injury. 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 200 hours time-in-service (TIS) after May 20, 2013 (the effective date of this AD) or within the next 12 months after May 20, 2013 (the effective date of this AD), whichever occurs first, do either (i) or (ii) as follows:
(i) Modify the left hand (LH) and right hand (RH) MLG leg shock absorbers P/N D60-3277-10-00 following either:
(A) The Instructions section of Diamond Aircraft Industries GmbH Work Instruction WI-MSB 42-095, MSB 42NG-026, Revision 1, dated February 5, 2013, and the Accomplishment/Instructions of Diamond Aircraft Industries GmbH Mandatory Service Bulletin MSB 42-095, MSB 42NG-026, dated November 11, 2011; or
(B) The Instructions section of Diamond Aircraft Industries GmbH Work Instruction WI-RSB 42-089, WI-RSB 42NG-017, Revision 2, dated February 12, 2013, and the Accomplishment/Instructions of Diamond Aircraft Industries GmbH Recommended Service Bulletin RSB 42 089/1, RSB 42NG-017/1, dated April 19, 2011.
(ii) Replace each MLG leg shock absorber P/N D60-3277-10-00 with a modified unit P/N D60-3277-10-00_01, following, as applicable: the Instructions section of Diamond Aircraft Industries GmbH Work Instruction WI-RSB 42-089, WI-RSB 42NG-017, Revision 2, dated February 12, 2013, and Diamond Aircraft Industries GmbH Recommended Service Bulletin RSB 42 089/1, RSB 42NG-017/1, dated April 19, 2011.
(2) After May 20, 2013 (the effective date of this AD), do not install an MLG leg shock absorber P/N D60-3277-10-00 on the airplane, unless the shock absorber has been modified following the instructions in either paragraph (f)(1)(i)(A) or (f)(1(i)(B) of this AD.
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.
