Airworthiness Directives; Airbus Helicopters Deutschland GmbH 
(AHD) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 and MBB-
BK 117 D-2 helicopters. This AD was prompted by report that a 
collective bellcrank-K was found incorrectly installed on a helicopter. 
This AD requires 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 a European Union Aviation Safety Agency (EASA) AD, which is 
incorporated by reference. This AD also allows installation of an 
affected collective bellcrank-K, provided certain instructions are 
followed. The FAA is issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective March 17, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 17, 
2022.

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.

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 ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 140 helicopters of U.S. 
Registry. The FAA estimates the following costs to comply with this AD.

                                                 Estimated Costs

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.
