Superseded. A later AD replaced this one: AD 2024-19-08. Comply with the one in force.
This AD applies to the following airplanes that:
(1) are certificated in any category; and
(2) are not equipped with a nose landing gear (NLG) leg part number (P/N) D41-3223-10-00_1 or higher (_2, _3, etc.).
| Model | Serial Nos. (S/N) |
|---|---|
| DA 40 | All S/Ns beginning with 40.006. |

| All S/Ns beginning with 40.FC001. |
We are adopting a new airworthiness directive (AD) for the products listed above to supersede an existing AD. 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:
Unless already done, do the following actions:
(1) Inspect the nose landing gear (NLG) leg for cracks within the next 12 months after September 25, 2007 (the effective date retained from AD 2007-17-06), or within the next 200 hours time-in-service (TIS) after September 25, 2007 (the effective date retained from AD 2007-17-06), whichever occurs later. Do the inspection following Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB40-046/1, No. MSBD4-046/1, dated April 25, 2007, or Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB40-046/3, No. MSBD4-046/3, dated November 17, 2008.
(2) If any cracks are found during the inspection required in paragraph (f)(1) of the AD or during any inspection required in paragraph (f)(2)(ii) or (f)(3) of this AD, replace the NLG leg before further flight. Do the replacement following Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB40-046/1, No. MSBD4-046/1, dated April 25, 2007; or Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB40-046/3, No. MSBD4-046/3, dated November 17, 2008.
(i) Replacing a NLG leg with a part number (P/N) D41-3223-10-00_1 or higher (_2, _3, etc.) terminates the repetitive inspections required in this AD.
(ii) Replacing a NLG leg with a P/N D41-3223-10-00 requires repetitive inspections as specified in paragraph (f)(3) of this AD until a P/N D41-3223-10-00_1 or higher (_2, _3, etc.) is installed.
(3) If no cracks are found during the inspection required in paragraph (f)(1) of this AD or a cracked NLG leg is replaced with a P/N D41-3223-10-00 NLG leg, repetitively inspect thereafter at intervals not to exceed 12 months or 200 hours TIS, whichever occurs later, until a P/N D41-3223-10-00_1 or higher (_2, _3, etc.) is installed. Do these repetitive inspections following Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB40-046/3, No. MSBD4-046/3, dated November 17, 2008.
(i) If a repetitive inspection occurs before June 17, 2009 (the effective date of this AD), then you may use Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB40-046/1, No. MSBD4-046/1, dated April 25, 2007.
(ii) All inspections that occur after June 17, 2009 (the effective date of this AD), must be done following Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB40-046/3, No. MSBD4-046/3, dated November 17, 2008.
(4) After installing a P/N D41-3223-10-00_1 or higher (_2, _3, etc.) as a replacement part, installing a NLG leg P/N D41-3223-10-00 is no longer allowed.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
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.
