SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0074, dated March 15, 2021 (EASA AD 2021-0074), to correct an unsafe condition for all Airbus Helicopters Deutschland GmbH (AHD) (formerly Eurocopter Deutschland GmbH; and Airbus Helicopters Inc., formerly American Eurocopter LLC) Model MBB-BK117 C-2 and MBB-BK117 D-2 helicopters. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. The NPRM published in the 
                    **Federal Register**
                     on November 26, 2021 (86 FR 67364). The NPRM was prompted by a report that a collective bellcrank-K (affected part) was found incorrectly installed on a helicopter. Subsequent investigations revealed that the affected part was an in-service replacement, and that the position marking on that part was incorrect. The NPRM proposed to require inspecting the collective bellcrank-K to determine if it is correctly installed and has a correct position marking and, depending on the findings, applicable corrective actions, as specified in EASA AD 2021-0074. The NPRM also proposed to allow installation of an affected collective bellcrank-K, provided certain instructions are followed. The FAA is issuing this AD to address incorrect installation of a collective bellcrank-K, which could lead to unwanted collective input, resulting in reduced control of the helicopter. See EASA AD 2021-0074 for additional background information.
                    ( print page 7702) Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. Conclusion These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. 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 these helicopters. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. Related Service Information Under 1 CFR Part 51 EASA AD 2021-0074 requires a one-time inspection of an affected part for correct installation by measuring the distance between the front edge of the bearing block and the front edge of the affected part, and for correct application of position markings, and, depending on the findings, accomplishment of applicable corrective actions. If an affected part is incorrectly installed, the corrective actions include inspecting for signs of chafing on the bearing block, the control lever, the forked lever, the sliding sleeve, and the bearing ring, replacing any parts that have signs of chafing, and installing a serviceable bellcrank-K with an applied position marking. If an affected part is correctly installed but the position marking is not correct, the corrective actions include re-working the affected part or replacing the affected part with a serviceable part that has an applied position marking. EASA AD 2021-0074 also allows installation of an affected part, provided certain instructions are followed. 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

 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, (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.
