AD 2013-08-21 Airworthiness Directives; Diamond Aircraft Industries Airplanes
Makes named: diamond. Models named: DA 40 NG. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to the following Diamond Aircraft Industries GmbH airplanes, certificated in any category: (1) Model DA 40 NG airplanes serial numbers 40.N001 through 40.N084; and (2) Model DA 40 NG airplanes, all serial numbers, that have been converted from the Model DA 40 D.
Compliance
Unless already done, do the actions specified in paragraphs (f)(1) through (f)(6). (1) Initially within the next 50 hours time-in-service (TIS) after May 21, 2013 (the effective date of this AD) or within the next 60 days after May 21, 2013 (the effective date of this AD), whichever occurs first, and repetitively thereafter at intervals not to exceed 50 hours TIS inspect, the charged air tubing from the turbocharger to the intercooler for chafing marks following the Accomplishments/Instructions section of Diamond Aircraft Industries GmbH Mandatory Service Bulletin 40NG-018/1, dated November 26, 2012. (2) If chafing marks are found on the charged air tubing during any inspection required in paragraph (f)(1) of this AD, before further flight, replace the charged air tubing with an airworthy part or modify the airplane with the improved design parts as specified in paragraph (f)(3) of this AD. Follow the Instructions section of Diamond Aircraft Industries GmbH Work Instruction WI-MSB-40NG-018, Revision 1, dated November 26, 2012, as specified in the Accomplishments/Instructions section of Diamond Aircraft Industries GmbH Mandatory Service Bulletin 40NG-018/1, dated November 26, 2012. If you choose to replace with an airworthy part instead of modifying the airplane as specified in paragraph (f)(3) of this AD, you must continue the repetitive inspections required in paragraph (f)(1) of this AD until the modification required in paragraph (f)(3) of this AD. (3) Within the next 200 hours TIS after May 21, 2013 (the effective date of this AD) or within the next 12 months after May 21, 2013 (the effective date of this AD), whichever occurs first, unless already done as the corrective action specified in paragraph (f)(2) of this AD, modify the airplane with the improved design parts. Follow the Instructions sections Diamond Aircraft Industries GmbH Work Instruction WI-MSB-40NG-018, Revision 1, dated November 26, 2012, as specified in the Accomplishments/Instructions section Diamond Aircraft Industries GmbH Mandatory Service Bulletin 40NG-018/1, dated November 26, 2012. (4) Modification of the airplane with improved design parts as specified in paragraph (f)(3) of this AD terminates the repetitive inspection requirements in paragraph (f)(1) of this AD. (5) After the modification specified in paragraph (f)(3) of this AD, do not install charge air elbow hose part number (P/N) SNS5X-O-60_72-90 °, charge air tube P/N D44-8126-00-05, or charge air hose P/N D44-8122-00-10 on any airplane. (6) After May 21, 2013 (the effective date of this AD), Diamond Aircraft Industries GmbH Recommended Service Bulletin 40NG-011, dated February 28, 2012, is no longer valid, and any actions following Diamond Aircraft Industries GmbH Recommended Service Bulletin 40NG-011, dated February 28, 2012, are prohibited.
Required actions
If, before May 21, 2013 (the effective date of this AD), you performed the actions in the Accomplishments/Instructions section of Diamond Aircraft Industries GmbH Mandatory Service Bulletin 40NG-018, dated November 22, 2012, you met the requirements of paragraphs (f)(1), (f)(2), and (f)(3) of this AD.
Unsafe condition
This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. We are issuing this AD to detect and correct chafing between the charge air tubing and the engine firewall that may cause a hole in the charge air tubing and could result in loss of charged air pressure with consequent loss of engine power and loss of control.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
