    ACTION:

    Final rule.

    SUMMARY:

    The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 helicopters. This AD was prompted by a report of an erroneous low rotor revolutions per minute (RPM) indication after establishing a one engine inoperative Start Printed Page 59414(OEI) condition. This AD requires a software (SW) modification for the aircraft management computer (AMC). The FAA is issuing this AD to address the unsafe condition on these products.

    DATES:

    This AD is effective October 27, 2020.

    The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 27, 2020.

    SUPPLEMENTARY INFORMATION:

    Discussion

    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 D-2 helicopters. The NPRM published in the Federal Register on April 28, 2020 (85 FR 23489). The NPRM was prompted by a report of an erroneous low rotor RPM indication after establishing an OEI condition. The NPRM proposed to require a SW modification for the AMC. The FAA is issuing this AD to address erroneous low RPM indications, which could cause the pilot to make inappropriate control inputs, resulting in damage to the helicopter or injury to occupants.

    The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0208, dated August 22, 2019 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 helicopters. You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-0342.

    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

    Airbus Helicopters has issued Alert Service Bulletin MBB-BK117 D-2-42A-005, Revision 3, dated June 6, 2019. This service information describes procedures for a SW modification for the AMC.

    This service information 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.

    Differences Between This AD and the MCAI or Service Information

    The MCAI provides a 60-day compliance time for accomplishing the SW modification. This AD requires completion of the SW modification within 50 hours time-in-service.

    Costs of Compliance

    The FAA estimates that this AD affects 30 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD:

    Estimated Costs for Required Actions

    Labor costParts costCost per productCost on U.S. operators
    1 work-hour × $85 per hour = $85$3,000$3,085$92,550

    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:Start Printed Page 59415

    (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.
