Airworthiness Directive · Amendment 39-15078 · Fuel
Diamond Aircraft Industries GmbH Model DA 40 Airplanes
This AD applies to Model DA 40 airplanes, serial numbers 40.006 up to and including 40.079, 40.081 up to and including 40.083, 40.201 up to and including 40.417, that:
(1) Are certificated in any category; and
(2) have fuel shaft part number D41-2823-20-00 Rev “-” installed.
We are adopting a new airworthiness directive (AD) for the products listed above. 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:
This inspection was initially addressed by Austrian AD A-2004-003. The design of the fuel selector/fuel valve universal joint has than been changed by design change MÄM 40-142/a and was introduced into serial production. The initial repetitive AD inspection interval of 50 Hrs is also applicable for this design. The investigation of the inspections carried out, has identified that the new joint design eliminated the design problem and no additional inspection is required.
Unless already done, do the following actions:
(1) When the airplane reaches a total of 200 hours time-in-service (TIS) or within the next 15 hours TIS after July 9, 2007 (the effective date of this AD), whichever occurs later, inspect the universal joint in accordance with Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 40-030/3, dated January 31, 2006. Repetitively inspect thereafter at intervals not to exceed 50 hours TIS until the modified universal joint assembly specified in paragraph (f)(2) of this AD is installed.
(2) Before further flight, replace the complete joint assembly with the new joint assembly, part number (P/N) D41-2823-20-00 rev “a” or higher in accordance with Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB 40-030/3, dated January 31, 2006, if one or more defects are found on the universal joint during any inspection required by this AD.
(3) The 50-hour TIS repetitive inspection requirement in paragraph (f)(1) of this AD is terminated when the universal joint has been replaced with the new universal joint assembly, P/N D41-2823-20-00 rev “a” or higher, as specified in paragraph (f)(2) of this AD.
(4) At 1,000-hour TIS intervals after the replacement specified in paragraph (f)(2) of this AD, inspect the universal joints in the fuel selector shaft as specified in Diamond Aircraft DA 40 Series Temporary Revision to the Airplane Maintenance Manual (AMM), AMM-TR-MÄM-40-142/a, Fuel Tank Selector, Doc. No. 6.02.01, Section 25-20-00, page 28a, dated May 23, 2005.
Note: This AD differs from the MCAI and/or service information as follows: The MCAI incorporates the repetitive inspection requirement for the new joint assembly, P/N D41-2823-20-00 rev “a” or higher, into the AMM. In order for this inspection to be required for U.S.-owner/operators, we are incorporating the 1,000-hour repetitive inspection into 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.
