Diamond Aircraft Industries GmbH Airplanes
This AD applies to all Diamond Aircraft Industries GmbH (DAI) Model DA 42, DA 42 NG, and DA 42 M-NG airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Diamond Aircraft Industries GmbH (DAI) Model DA 42, DA 42 NG, and DA 42 M-NG airplanes. This AD was prompted by several reports of passenger door separation from the fuselage. This AD requires revising the existing airplane flight manual (AFM) for your airplane to provide the flight crew with revised operating limitations, emergency procedures, and normal operating procedures; modifying the airplane; and repetitively inspecting the door latching and safety hooks for correct engagement, foreign objects, damage (including but not limited to corrosion and wear that exceeds specified limits), and proper function. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Within 50 hours time-in-service (TIS) or 50 days, whichever occurs first after the effective date of this AD, revise the existing AFM for your airplane to include the information specified in the applicable AFM temporary revision specified in paragraphs (g)(1) through (4) of this AD appropriate for your airplane model.
(i) The owner/operator (pilot) holding at least a private pilot certificate may revise the existing AFM for your airplane and must enter compliance with the applicable paragraph of this AD into the airplane maintenance records in accordance with 14 CFR 43.9(a) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
(ii) The AFM revision required by paragraph (i)(1) of this AD may be accomplished before the initial inspection and modification required by paragraph (i)(2) of this AD for that airplane.
(2) Within 50 hours TIS or 50 days, whichever occurs first after the effective date of this AD, accomplish the initial inspection of the safety hook, safety hook spring, retaining bracket, safety hook actuation pin, latching mechanism spring, latching bolts, and gas spring and the modification of the airplane with placards in accordance with the instructions of Section III, steps 2 through 4, 6, 7, 9 through 11, 13, 14, 16, 18, 19, 21 through 23, and 25 through 36 in the Diamond Aircraft work instruction specified in paragraph (f) of this AD.
(3) Within 200 hours TIS or 12 months, whichever occurs first after the initial inspection required by paragraph (i)(2) of this AD, and thereafter at intervals not to exceed 210 hours TIS or 13 months, whichever occurs first, accomplish the repetitive inspections of the airplane in accordance with the instructions of Section IV, steps 2 through 6, of the Diamond Aircraft work instruction specified in paragraph (f) of this AD.
(4) If, during any inspection as required by paragraph (i)(2) or (3) of this AD, any findings, as defined in Section III, steps 2 through 4, 6, 7, 9 through 11, 13, 14, 16, 18, 19, 21 through 23, and 25 through 36, and Section IV, steps 2 through 5, of the Diamond Aircraft work instruction is identified, before further flight, accomplish the applicable corrective action(s) in accordance with the instructions of Section III, steps 2 through 4, 6, 7, 9 through 11, 13, 14, 16, 18, 19, 21 through 23, and 25 through 36, and Section IV, steps 2 through 5, of the Diamond Aircraft work instruction specified in paragraph (f) of this AD. Where instructed to contact the manufacturer “in case of doubt” or for approved instructions, this AD requires before further flight using instructions approved by the Manager, International Validation Branch, FAA; the European Union Aviation Safety Agency (EASA); or DAI's EASA Design Organization Approval (DOA) and within the compliance time specified therein, accomplishing those instructions. If approved by the DOA, the approval must include the DOA-authorized signature.
(1) Within 30 days after performing the initial inspection required by paragraph (i)(2) of this AD or within 30 days after the effective date of this AD, whichever occurs later, report the results of the initial inspection, including no findings, to DAI. The report must include the information specified in Appendix B of the Diamond Aircraft work instruction specified in paragraph (f) of this AD.
(2) Report the results of each repetitive inspection required by paragraph (i)(3) of this AD, including no findings, to DAI within 30 days after that inspection. The report must include the information specified in Appendix B of the Diamond Aircraft work instruction specified in paragraph (f) of this AD.
