 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW109SP helicopters. This AD was prompted by reports of corrosion inside the hoist support assembly (boom assembly) (affected part) that affects both the huck bolt heads (blind bolt fasteners) and the support surface. This AD requires repetitive inspections of the external and internal surfaces of each affected part for cracking and corrosion and, depending on the findings, accomplishment of corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective May 11, 2022. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 11, 2022.

SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0179, dated July 27, 2021 (EASA AD 2021-0179), to correct an unsafe condition for Leonardo S.p.A. Helicopters, formerly Finmeccanica S.p.A., AgustaWestland S.p.A., and Agusta S.p.A., Model AW109SP helicopters, all serial numbers. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Leonardo S.p.a. Model AW109SP helicopters. The NPRM published in the 
                    **Federal Register**
                     on January 21, 2022 (87 FR 3241). The NPRM was prompted by reports of corrosion inside the hoist support assembly affecting both the huck bolt heads and the support surface. Investigation of the root cause for the corrosion is ongoing. The NPRM proposed to require repetitive inspections of the external and internal surfaces of each affected part for cracking and corrosion and, depending on the findings, accomplishment of corrective actions, as specified in EASA AD 2021-0179. The FAA is issuing this AD to address corrosion on the hoist support assembly. This condition, if not addressed, could affect the structural integrity of the hoist support assembly, leading to in-flight detachment of the hoist support and consequent damage to the helicopter, and injury to hoisted persons. See EASA AD 2021-0179 for additional background information. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs.
                    ( print page 19794) 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 2021-0179 requires repetitive inspections of the external and internal surfaces of each affected part for cracking and corrosion and, depending on the findings, accomplishment of corrective actions. If there is no evidence of corrosion on the interior surface of the boom torque tube or on the huck bolt heads, the corrective actions include spraying the interior surface with corrosion preventative compound around the hulk bolt heads from the forward and aft ends of the boom torque tube, and installing new tube plugs on both ends of the boom torque tube. If there is superficial corrosion on the interior surface of the boom torque tube or on the hulk bolt heads, the corrective actions include cleaning the corrosion, spraying the interior surface with corrosion preventative compound, and installing new tube plugs on both ends of the boom torque tube. If corrosion is found that is not superficial corrosion, the corrective action is repair or replacement of the boom torque tube. If cracking is observed on the external surface of the hoist support assembly the corrective action is replacement of the hoist support assembly. If only corrosion is found on the external surface of the hoist support assembly the corrective actions include cleaning the hoist support assembly. EASA AD 2021-0179 also allows installing an affected part, provided certain instructions are followed.

 The FAA has received no definitive data on which to base the cost estimates for the repairs specified in this AD. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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.
