 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2023-1881; Project Identifier MCAI-2023-00495-T; Amendment 39-22609; AD 2023-23-07]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Deutsche Aircraft GmbH Model 328-100 and 328-300 airplanes. This AD was prompted by a manufacturer's design review, which identified a potential risk of the rudder control rod buckling during operation with one engine inoperative during take-off and landing phases. This AD requires visually inspecting the rudder control rod, performing a one-time functional check of the rudder control rod, performing corrective actions if necessary, and reporting the inspection results, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective January 16, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 16, 2024.

SUPPLEMENTARY INFORMATION:  Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
                    ( print page 86035)
                    part 39 by adding an AD that would apply to all Deutsche Aircraft GmbH (Type Certificate Previously Held by 328Support Services GmbH; AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and 328-300 airplanes. The NPRM published in the 
                    **Federal Register**
                     on September 14, 2023 (88 FR 63036). The NPRM was prompted by AD 2023-0065, dated March 20, 2023, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2023-0065) (also referred to as the MCAI). The MCAI states that during a design review of the rudder control architecture, it was discovered that the rudder control rod could buckle during operation with one engine inoperative during take-off and landing phases. This condition, if not detected and corrected, could result in reduced control of the airplane. In the NPRM, the FAA proposed to require visually inspecting the rudder control rod, performing a one-time functional check of the rudder control rod, performing corrective actions if necessary, and reporting the inspection results, as specified in EASA AD 2023-0065. The NPRM also proposed to limit the installation of affected parts under certain conditions. The FAA is issuing this AD to address the potential failure of a rudder control rod. You may examine the MCAI in the AD docket at 
                    *regulations.gov*
                     under Docket No. FAA-2023-1881. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 EASA AD 2023-0065 specifies procedures for a functional check and general visual inspection (GVI) of the rudder control rod (measuring the length of the rudder control rod, inspecting for signs of bending, ensuring both rudder control rod ends are symmetrically adjusted, and ensuring the threads of the rod end fully cover both inspection holes). Depending on the inspection results, EASA AD 2023-0065 also specifies corrective action, including obtaining and following instructions if any discrepancy is identified. EASA AD 2023-0065 also requires reporting the inspection results to Deutsche Aircraft GmbH and limits the installation of affected parts under certain conditions. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the 
                    **ADDRESSES**
                     section. Interim Action The FAA considers that this AD would be an interim action. If final action is later identified, the FAA might consider further rulemaking then. Costs of Compliance The FAA estimates that this AD affects 54 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Costs for Required Actions
Labor cost
Parts cost
Cost per 
                             product
Cost on U.S. 
                             operators2 work-hours × $85 per hour = $170
$0
$170
$9,180
 The FAA has received no definitive data on which to base the cost estimates for the on-condition actions specified in this AD. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a currently valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to take approximately 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority. The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a “significant regulatory action” under Executive Order 12866,
                    ( print page 86036) (2) Will not affect intrastate aviation in Alaska, and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
