FOR FURTHER INFORMATION CONTACT : Mahmood G. Shah, Aviation Safety Engineer, Fort Worth ACO Branch, FAA, 10101 Hillwood Pkwy., Fort Worth, TX 76177; phone: 817–222– 5538; email: mahmood.g.shah@faa.gov. SUPPLEMENTARY INFORMATION : Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0157, dated July 3, 2019 (EASA AD 2019–0157) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for Airbus Helicopters Model SA330J 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 Airbus Helicopters Model SA330J helicopters, all serial numbers. The NPRM published in the Federal Register on April 13, 2021 (86 FR 19157). The NPRM was prompted by reports of the failure of the lower bearing cage of the MRH flapping hinges and of the presence of metallic particles at the bottom of a drag hinge. The NPRM proposed to require repetitive inspections of the MRH chip detectors, or for helicopters not equipped with chip detectors, repetitive inspections of the oil for contamination by metallic particles, and corrective actions if necessary, as specified in an EASA AD. The FAA is issuing this AD to address failure of the lower bearing cage of the MRH flapping hinges and presence of metallic particles at the bottom of a drag hinge, which could lead to loss of flapping hinge function, resulting in MRH unbalance and loss of control of the helicopter. See the MCAI for additional background information. Discussion of Final Airworthiness Directive Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 EASA AD 2019–0157 specifies procedures for repetitive inspections of the MRH chip detectors, or for helicopters not equipped with chip detectors, repetitive inspections of the oil for contamination by metallic particles, and corrective actions if necessary. Corrective actions include replacement of the incidence hinge bearings, replacement of the flapping bearing race and bearing or if there is no degradation reinstallation of the bearing race and bearing 180 ° from the marked position during removal, and replacement of the drag lower bearing race and bearing. 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 this AD interim action. The investigation to detect the root cause of the reported failures of the lower bearing cage of the MRH flapping hinges and presence of metallic particles at the bottom of the drag hinge is on-going. Costs of Compliance The FAA estimates that this AD affects 4 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: E STIMATED C OSTS FOR R EQUIRED A CTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 .......................................................................................... $0 $340 $1,360 The FAA estimates the following costs to do any necessary on-condition replacements that would be required based on the results of any required actions. The FAA has no way of determining the number of helicopters that might need these on-condition replacements: E STIMATED C OSTS OF O N -C ONDITION A CTIONS Labor cost Parts cost Cost per product 24 work-hours × $85 per hour = $2,040 ................................................................................................................. $53,025.29 $55,065.29 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 VerDate Sep<11>2014 16:15 Jul 09, 2021 Jkt 253001 PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 E:\FR\FM\12JYR1.SGM 12JYR1 khammond on DSKJM1Z7X2PROD with RULES
